What makes you think you might be bipolar?
A manic episode for me usually starts with being unable to sleep. I start having more energy and confidence. It's the only disease I know of where the first sign of a return of the disease is a really good mood. For me it makes feeling good scary.
As things progress I tend to get much more spiritual, but it's not in line with my usual beliefs. In my mind I become the center of everything. I believe that I am influencing what happens on tv and that everything they are saying relates to me. These are common experiences for people with bipolar, although as I understand it, bipolar II doesn't have the delusions that I experience.
Hope that's helpful
