Bipolar disorder is known for its extreme highs and lows. It is also called manic depression.
When your mood is ‘up’, you’ll experience episodes of high energy. You will feel unusually happy, engaged or motivated. This is called mania or hypomania. In this phase, it’s possible you will make poor or rash decisions without much thought to the consequences. You also might not sleep much.
When you’re ‘down’, you’ll have most of the symptoms of major depression. You will feel extreme negative about life and cry a lot. You won’t be making much eye contact with anybody. There’s a high probability of self harm or even suicide.
