Depressive episode
A sustained period of low mood, low energy, and loss of interest.
A depressive episode is a period of at least two weeks with persistently low mood or anhedonia — loss of pleasure — together with changes in sleep, appetite, energy, concentration or how you see yourself.
In bipolar disorder these account for far more days than the highs do, and they are what most people seek help for. It is a large part of why bipolar gets diagnosed as ordinary depression so often: the depression looks the same from outside, but what treats it safely is different.
Bipolar depression can also carry features of a high at the same time — agitation, racing thoughts, being unable to sit still. That combination is called mixed features, and it is a reason to contact your prescriber early rather than wait for it to pass.
Depression also brings thoughts about death, or about not wanting to be here. That is a symptom, not a verdict, and it is a reason to get help now rather than later — our crisis page lists numbers by country.
