I have always been told the line is very fluid. So it could be at a point that requires hospitalization, or at the point that you are being self-destructive without a second thought as to why you are doing it. (For example maybe you are spending all of your money at the casino, or you just found yourself on a road trip to some place without out reason, or perhaps you just got into a fight for no reason).

What you are describing sounds like me so much. I also have been accused of being on drugs, talk 90 mph, take on these crazy projects, getting into shouting matches with people who control my future, and so on. These were things that I have worked out to be associated with my manic episodes.

My hypo episodes just seem to be more of an inflated self-esteem, everything is peachy, just not really caring about what others think, lots of energy, and not really needing a whole lot of sleep.

I hope this makes sense and helps somewhat.
