Major depressive disorder typically manifests as persistent low mood or a marked loss of interest in most activities for at least two weeks. It is often accompanied by decreased energy, sleep disturbances, changes in appetite, impaired attention, low self-esteem, and intense guilt; in severe cases, it can lead to self-harm or suicidal ideation. Unlike ordinary sadness, it has a wider impact and lasts longer, often interfering with learning, work, interpersonal relationships, and daily self-care. Some people may exhibit marked crying and despair, while others may experience numbness, lethargy, or a feeling of heaviness, as if their entire being is being crushed. Key identification points include: a low mood lasting more than two weeks, a near-complete loss of interest in life, a feeling of heaviness both mentally and physically, significantly disrupted sleep, and recurring self-blame. If these states persist, they should not be simply attributed to a lack of effort but should be taken seriously. When necessary, seek psychological counseling, psychiatric evaluation, and practical support, especially when thoughts of self-harm arise. Before taking the test, reflect on your overall state over the past two weeks, rather than just focusing on whether you feel better today. Some depression can be hidden beneath a seemingly normal exterior for a long time, so allow yourself to answer honestly. The earlier you recognize it, the better your chances of receiving appropriate help. Please treat this as a gentle identification exercise, not as labeling yourself. Accurately naming your condition will provide clearer direction for subsequent support and repair. You don't need to rush to judge yourself; simply be honest about your current state. If the pain significantly worsens, or you experience self-harming thoughts, please contact professional help offline promptly. Understanding your condition isn't about fear, but about taking better care of yourself. This understanding will help you progress more steadily through subsequent tests.

Persistent depressive disorder (PDD) is characterized by a lower intensity of depression that may not be as severe as major depressive disorder, but lasts for a long time. A person may remain in a gloomy, low-energy, and hopeless state for years, still able to maintain basic living habits, but rarely feeling truly energetic. Common symptoms include chronic fatigue, lack of confidence, low self-esteem, pessimism, decreased interest, decreased attention, and unstable sleep or appetite. Because it doesn't necessarily manifest as an obvious breakdown, it's easily overlooked by those around them, and the person experiencing it may mistake it for a personality trait. Key identification points are: whether this low mood has persisted for many years, whether there's a long-term feeling of having no expectations for life, and whether functional abilities remain but the heart remains empty. Persistent depression is not a minor issue; it slowly erodes a sense of life and motivation. Before taking the test, please reflect on your state over a longer period, not just the last few days. If you find that you haven't been truly happy in a long time, this in itself is an important clue. Recovery from this type of depression often requires patience, as it doesn't develop overnight and is difficult to change with a single act of resilience. A regular lifestyle, stable support, psychological counseling, and gradually restoring interests can all be important help. Prolonged gloom also deserves to be carefully acknowledged. Please treat this as a gentle identification exercise, not as labeling yourself. When your condition is accurately named, subsequent support and repair will have a clearer direction.

Postpartum depression typically appears weeks to months after childbirth, and its symptoms are more severe and last longer than typical postpartum mood swings. Common symptoms include persistent low mood, crying, anxiety, insomnia, lack of emotional connection with the child, intense self-blame, fear of not being a good mother, and feelings of helplessness in feeding and care. Some women feel numb, like they are mechanically performing tasks; others feel overwhelmed by the baby's cries, physical recovery, family expectations, and the change in identity. Postpartum depression does not mean the mother doesn't love her child, nor is it a moral failure; rather, it is an imbalance in the body and mind caused by the immense changes. Key identification points include: persistent low mood for months after childbirth, lack of joy or connection with the child, intense self-blame, significant anxiety, or numbness. If thoughts of harming oneself or the child arise, contact family, a doctor, or emergency services immediately. Postpartum depression requires support, not shaming. Before testing, gently review your sleep, support, mood, and physical recovery during this period. Mothers also need to be cared for, not just expected to be strong. When caregivers receive support, family relationships are more likely to stabilize. Please treat this as a gentle identification exercise, not as labeling yourself.

Seasonal affective disorder (SAD) is a type of depression associated with seasonal changes, often worsening in autumn and winter when sunlight is reduced. Symptoms may include low mood, somnolence, fatigue, decreased activity, increased appetite, weight gain, social withdrawal, and lack of energy. These symptoms may gradually improve in spring or after increased sunlight. Key identification features include: recurring low mood in similar seasons each year; significant changes in sleep and appetite; a close relationship between mood and sunlight exposure; and impact on work, studies, or interpersonal life. It's not simply a matter of feeling cold or being lethargic, but rather a response of the biological rhythms and emotional system to seasonal influences. Before testing, reflect on whether your low mood follows a clear seasonal pattern, whether you feel sleepier, go out less, or find it harder to feel happy in winter. If a pattern is clear, you can plan ahead for sun exposure, regular exercise, social connection, and professional counseling. The key to seasonal affective disorder is early identification and proactive preparation. If you find yourself consistently feeling significantly depressed in a particular season, don't blame yourself for lacking energy. Consider it a sign from your body and mind's rhythms that you need more sunlight, activity, and a stable routine. Prepared care can reduce the emotional impact of seasonal changes. Please treat this as a gentle identification exercise, not as labeling yourself. Accurately naming your condition will provide clearer direction for subsequent support and repair. You don't need to rush to judge yourself; simply be honest about your current state.

Premenstrual anxiety and depression (PMDD) is a severe mood disorder that occurs before the menstrual cycle, significantly more intense than typical premenstrual discomfort. Common symptoms include extreme irritability, mood swings, anxiety, low mood, hopelessness, difficulty concentrating, physical discomfort, and increased interpersonal conflict, which usually subside after menstruation begins. The key to identification is cyclicality: do symptoms occur at similar times each month, are they highly synchronized with the menstrual cycle, and do they significantly affect work, relationships, or daily functioning? PMDD is not simply bad temper, nor should it be dismissed as premenstrual mood swings. It may be related to hormonal fluctuations affecting the mood regulation system and needs to be carefully documented and evaluated. Before testing, review your cycle changes over the past few months, recording your mood, sleep, appetite, physical pain, and relationship conflicts. If you experience recurring intense low mood, hopelessness, or impulsivity each month, seek professional help promptly. Recognizing cyclical patterns is the first step in self-care. Documentation is crucial for this type of distress because it helps distinguish between chronic depression, general stress, and obvious cyclical changes. When patterns are recognized, interventions are more precise. Your menstrual cycle is not shameful, but a vital rhythm that needs to be understood. Please treat this as a gentle identification exercise, not as labeling yourself. Accurately naming your condition will provide clearer direction for subsequent support and repair. You don't need to rush to judge yourself; simply be honest about your current state.

Masked depression is characterized by low mood that may not be overt but rather manifests through physical symptoms and behaviors. Common forms include chronic pain, insomnia, gastrointestinal discomfort, appetite disturbances, fatigue, irritability, social conflict, sudden breakdowns, or aggressive reactions. Some people repeatedly focus on physical ailments while ignoring emotional stress; others may appear normal, even capable, yet suddenly break down at certain times. Masked depression often occurs in people who are poor at expressing emotions, habitually suppress their vulnerability, and chronically bear stress. Key identification points include: persistent but unexplained physical symptoms, limited emotional expression, a tendency to express pain through actions, and seemingly resilient yet frequently on the verge of collapse. Before testing, don't just ask yourself if you are sad; also ask yourself: Has my body been bearing the burden for me for a long time? Do I express my low mood through anger, silence, procrastination, or avoidance? Recognizing hidden signals can help depression gradually emerge from the body and relationships. Necessary medical examinations are important, but if physical problems recur and are highly correlated with stress, psychological factors should also be considered. This doesn't mean that physical sensations are false, but rather that the body may be expressing a true emotional burden. When the body is understood, the heart will also find an outlet. Please treat this as a gentle identification exercise, not as labeling yourself. When the state is accurately named, subsequent support and healing will have more direction. You don't need to rush to judge yourself; just honestly see your current state.

Recurrent depressive disorder refers to the occurrence of more than one depressive episode, with periods of relative normality or remission in between. A person may experience significant depression, improve, but relapse after unemployment, heartbreak, loss, illness, chronic stress, or seasonal changes. Key identification points include: a clear history of depression, recurrent episodes of low mood, episodes related to stress or physical condition, and a recurrence of a similar pattern after the first episode. Recurrent depression can be particularly disheartening, making one feel like they're incapable of overcoming it. In reality, relapse doesn't indicate failure, but rather the need for a more comprehensive long-term maintenance plan. In addition to receiving professional support during episodes, during periods of stability, it's crucial to focus on regular sleep patterns, exercise, social connection, stress management, and early warning signs. Before testing, reflect on past periods of low mood: Have you experienced similar cycles? What common triggers precede each episode? Early detection of warning signs can help prevent serious deterioration. Relapse doesn't mean previous efforts were in vain. Many mental states require long-term care, just as chronic physical problems require ongoing management. As you learn to recognize your relapse patterns, you gradually gain more control. Stability isn't about never fluctuating, but about knowing how to return to support when fluctuations occur. Please treat this as a gentle identification exercise, not as labeling yourself. When your condition is accurately named, subsequent support and repair will have a clearer direction. You don't need to rush to judge yourself; just honestly acknowledge your current state.

Bipolar depression, the depressive phase of bipolar disorder, is often mistaken for ordinary depression. It may manifest as low mood, slowness, excessive sleep, decreased energy, loss of interest, and heaviness. Crucially, patients may have experienced manic or hypomanic episodes in the past or present. Hypomania is not necessarily distressing and can even be mistaken for a state of well-being: sudden increases in energy, decreased sleep needs, increased talking, rapid thinking, impulsive spending, increased risk-taking behavior, excessive confidence, and abnormally high or low mood. Ignoring these historical patterns while focusing solely on depressive episodes can easily lead to misdiagnosis. Key identification points include: whether there have been brief episodes of manic or energetic outbursts, the intensity of mood swings, whether the depression has abrupt onset and cessation, and whether there is a family history of bipolar disorder or severe mood disorders. If these clues are found before testing, it is recommended to seek evaluation by a psychiatrist or professional psychological expert. Accurate differentiation of bipolar depression is essential for safer intervention. It is especially not recommended to draw conclusions based solely on online tests, as bipolar disorder involves medication and risk management. If there are significant alternations between mania, impulsivity, decreased sleep, and depression, professional evaluation should be sought as soon as possible. Accurate identification is a crucial step in protecting oneself. Please treat this as a gentle identification exercise, not as labeling yourself. Accurately naming your condition will provide clearer direction for subsequent support and repair. You don't need to rush to judge yourself; simply be honest about your current state.

Reactive depression is typically triggered by specific life events, such as heartbreak, unemployment, bereavement, illness, family conflict, major failure, or real-world stress. Its emotional content often corresponds to the event itself, including feelings of sadness, despair, loss of control, anger, shame, or helplessness. It doesn't appear out of nowhere but is a natural psychological reaction to real-world trauma. Key identification points include: whether depressive symptoms are highly correlated with a particular event, whether they appeared shortly after the event, whether the emotions revolve around the event, and whether they affect sleep, appetite, work, and relationships. Reactive depression can sometimes gradually improve with support, time, and adjustment to reality, but if it persists for a long time, worsens, or involves intense feelings of despair and self-harm, seeking help is necessary. Before testing, reflect on any recent significant changes. Understanding the relationship between the event and the emotions is not about dwelling on the past, but about finding more appropriate support. In this type of depression, supportive listening, grief processing, access to real-world resources, and stable companionship are all important. Don't expect yourself to recover from a major blow immediately. True recovery is about slowly regaining your footing through understanding. Treat this as a gentle identification exercise, not as labeling yourself. When your condition is accurately named, subsequent support and repair will have a clearer direction.

Depression manifests differently at different ages. Adolescent depression is often mistaken for rebellion and may present as irritability, academic withdrawal, declining grades, internet addiction, reduced social interaction, sleep disturbances, impulsive behavior, or self-harm tendencies. They may not be able to clearly express their sadness but may use aggression, silence, or avoidance to express their pain. Depression in the elderly is often mistaken for aging or physical problems and may manifest as chronic pain, fatigue, poor sleep, changes in appetite, decreased interest, memory and attention deficit, feelings of hopelessness, and loneliness. The elderly may not express their feelings but repeatedly mention physical discomfort or feelings of worthlessness. Identification requires considering age, life events, physical condition, and social support. For adolescents, don't just blame their behavior; for the elderly, don't just tell them to "think positively." Before testing, observe whether mood changes are affecting learning, daily life, self-care, and safety. If there is a risk of self-harm, seek help immediately. Both groups especially need family and social support because their suffering is often not expressed in typical language. More listening, companionship, and professional evaluation can prevent more serious consequences. Being seen is an important protective factor. Please treat this as a gentle identification exercise, not as labeling yourself. Accurately naming your condition will provide clearer direction for subsequent support and repair.
