Bipolar Disorder Support Group
Bipolar disorder is not just a single disorder, but a category of mood disorders marked by periods of abnormally high energy and euphoria, often accompanied by bouts of clinical depression. This is the place to talk about your experience with bipolar disorder, learn from others' experiences, and find support.
Most-if not all- of the behaviors you have described can be attributed to mania. I also had a therapist who said I was misdiagnosed- that I wasn't bipolar. Sounds very possible that you are, but a trained Psychiatrist should make that call. A second and even 3rd opinion sound like a good plan.
