I know what you mean...I'm in a similar situation where I can hardly believe that I really have bipolar 1. It's been 5 years since I had a full-blown manic episode, and it's been almost 4 since I was hospitalized for SI. No extreme mood episodes at all, just mild depression and (more often) hypomania in between long periods of stability. It does make me question my diagnosis and wonder if I really need to be on so many medications. But that too is a sign of trouble, so we both ought to work on being more down to earth.
