- In a manic episode, a teen feels euphoric, has high self-esteem and feels he can accomplish anything. He may also have more energy and be more prone to reckless behavior, such as driving fast or experimenting with drugs or alcohol.
- With depression, a teen feels hopeless and worthless. She is angry, sleeps and eats too much or too little, and may have thoughts of ending her life.
- Hypomania is a symptom of bipolar 2, a less severe mood disorder that does not have the extreme highs of mania. A teen may feel optimistic, but he is still able to function as usual.
- With some teens, they have the symptoms of mania or hypomania and depression simultaneously. During this period, a teen feels energetic but also hopeless and irritated.
- In rapid swinging or cycling, a teen quickly alternates from manic symptoms to depressive symptoms and back again. Each phase can last a few hours or one to two days.
