A bipolar disorder is a mental illness. With a bipolar disorder, one's mood can change in different ways.

One's mood may be high. Then you will have a lot of energy and feel extremely capable. As a result, you can overestimate yourself. One may also be irritable or behave abnormally. For example, you might be very talkative, restless, or require little sleep.

You can also be depressive due to a bipolar disorder. Your mood is then down. You feel very low, for example, and you stop enjoying things. You may feel exhausted and find everyday activities harder than before. You can lose interest in things which you previously enjoyed. They may also be finding it harder to concentrate and they may have lost confidence in themselves.

The condition can seriously affect one's everyday life, work or private life. For a long time you may have no symptoms from the disorder.
