Bipolar disorder (sometimes called manic depression) is a mental health condition wherein people experience extreme highs called mania and intense low periods of sadness or depression. These phases of mania and depression are called episodes and can shift rapidly.
Manic Highs: Experiences that include intense happiness, irritability, high self-esteem, decreased sleep, racing thoughts, reckless behavior (unrestrained shopping sprees, foolish business investments, driving very fast, sexual indiscretions and abuse of alcohol or drugs), initiating multiple projects without finishing them as one gets easily distracted, talking very fast or more than usual, increased energy, pacing and restlessness.
Depressive Lows: These are characterized by sadness (sometimes with crying episodes for no particular reason), fatigue, generalized body aches, loss of interest in all pleasurable activities, fluctuating appetite or sleep from high to low, lack of motivation, random suicide thoughts, excessive inappropriate guilt, feelings of hopelessness and worthlessness.
If you have manic highs and depressive lows, you need to seek treatment from a professional to avoid the social, occupational and family impairments that could occur in untreated cases.
