I don't use the word crazy in the context of describing myself or anyone else with mental health issues. I find it pretty offensive in that context, kind of like I detest the term "retard". It's just not right.

I don't very often refer to myself in terms of my mental illness. When I speak of my diagnosis, I say "I have bipolar disorder" rather than "I am bipolar." It is a subtle distinction, but an important one. I would never say "I am cancer" or "I am hemmorhoids," so why say "I = my disorder?"
