Just to add , that when I am up I am very positive and this has got me a lot of good business , so would I change my condition ? . . . . . . not on your life LOL 
Ive heard it said that the highs the individual experiences with bi-polar are what makes the condition bearable, in fact although the lows are dreadfully dreadfully, debilitating and depressingly low the highs are just fabulous, like that of a drug induced ecstacy.
The trouble is that some people can become very divorced from reality on the highs. I know that spending money one hasn't got can be a major symptom of them (I don't mean to the degree that many people do it but something far more excessive). One person in particular who I knew had severe delusions on high phases but I won't write them here as it would break a confidence. I would add that she was far worse when not taking her medication.

6 months I blew 10k when I was 17 in less then three had a great time but oh how I have grown up
