Mood swings are not just occasional bad moods or being short-tempered. They can manifest as elevated mood, low mood, irritability, emptiness, sensitivity, sudden outbursts, or difficulty regaining balance. When mood changes affect sleep, relationships, judgment, work, and daily life, they deserve serious attention. This section will help you understand the characteristics of different mood swing issues, reduce self-blame, and prepare you for subsequent tests.

The core of bipolar I disorder is the occurrence of a significant manic episode. During a manic episode, a person may experience abnormally high energy, sleep very little without feeling tired, talk excessively, be impulsive, have inflated self-confidence, and even make high-risk decisions; afterwards, they may also experience a depressive slump. This column helps you distinguish between ordinary excitement and manic states, and observe whether the emotional peak has significantly affected your life, relationships, and judgment.

Bipolar II disorder typically presents as alternating depressive episodes and hypomanic states. Hypomania is not as severe as mania; it may simply manifest as increased energy, talkativeness, rapid thinking, decreased sleep, and impulsiveness, making it easy to mistake for a good state of mind. However, the subsequent low mood, fatigue, and despair can be quite pronounced. This section helps you identify those subtle mood spikes and their connection to depressive troughs.

Cyclic mood disorder is a long-term, recurring, mild but persistent fluctuation in mood. A person may experience periods of heightened energy, active thinking, and elevated mood, followed by periods of depression, fatigue, and self-doubt, but these may not meet the criteria for typical mania or major depression. Because the fluctuations are relatively mild, they are often mistaken for mood swings. This column helps you see these long-term mood cycles and understand their impact on your life rhythm and sense of self.

Borderline personality disorder is often characterized by intense mood swings, fear of abandonment, fluctuating relationships, unstable self-esteem, and impulsive behavior during periods of distress. It's not about having a "bad personality," but rather a long-term struggle with inner security and emotional regulation. This column will help you understand the pain behind sensitivity, intensity, emptiness, and unstable relationships, and teach you to observe yourself more gently.

Disruptive mood disorders are common in children and adolescents, primarily characterized by persistent irritability, frequent emotional outbursts, and reactions that significantly exceed the intensity of the event itself. The child may not be intentionally disobedient, but rather their emotional system lacks stable regulatory capabilities. This section helps parents and learners understand the psychological and physical reasons behind persistent irritability, outbursts, and loss of control, reducing blame and increasing support and structured guidance.

Emotion regulation disorder refers to the difficulty a person has in recognizing, expressing, calming, or restoring balance after emotions arise. It may manifest as breaking down over minor things, a sudden outburst after long-term suppression, or lingering in sadness, anger, or anxiety for an extended period. This column will help you understand the process of emotion regulation and realize that emotions are not the enemy, but rather internal signals that need to be heard, named, and properly addressed.

Before taking the test, please gently reflect on your recent emotional state: Have you experienced sudden highs or lows? Has it affected your sleep, relationships, work, studies, or impulsive decisions? Do you often feel regret, guilt, or exhaustion afterward? There's no need to embellish or exaggerate; just answer as truthfully as possible. This section helps you approach the test with stability and honesty, making the results closer to your actual situation.
