I think you might have helped me solve a riddle I've been dealing with for a very long time. I do notice that I tend to say the most... well, lets just say I know what the term "word vomit" really means! But I do it mostly in situations where I don't feel comfortable or "accepted" by the people around me. I sometimes intentionally use my "crazy" to sift out those people who just can't handle or understand someone who's brain doesn't work like theirs, but in times where I can't do that, it amps me up and suddenly I'm giving them unrelated facts and figures, or telling "funny" jokes, or a story about how when I was 5 I ate a bug.

When I catch myself going on and on and on in a truly hypo manic state (and my mom has called me on it before) I've learned to pinch my wrist. It's almost an automatic response now. Helps ground me.
