Bipolar disorder varies tremendously from person to person. Some people are mostly depressed. Others are mostly manic, and others are mixed. Some have rapid cycles, and others have episodes far apart.

The definitive feature of bipolar disorder is mania. I tend to stay on the manic end of the spectrum. Do a quick search on mania, and you will get a long list of symptoms associated with it. I have bipolar type 1, which has extreme mania symptoms, including grandiosity and psychotic features. I thought I was literally God, in the climactic peak of my most extreme manic episode. That is about as extreme as mania gets!
