Yes. I have often thought that I may not have Bipolar. I don't have to be completely manic to think like that either. I rapid cycle, so those feelings of being completely normal are short lived, and when depression strikes, I have no doubt at all and am glad I continued taking my mood stabilisers.

I think, sometimes, that just forgetting how overwhelmed or out of control I felt at some stage is part of my problem (my forgettory is stronger than my memory), rather than denial or anosognosia or anything like that. It only takes a small dip or rise in a cycle to dispel my false sense of security.

So I don't think it is a question of craziness or sanity.
