My boyfriend suffers from clinical depression. He also goes through short periods of mania, although he's never been classified as bi-polar, because the mania is very mild and only lasts for a few hours at the most.
For some reason, I've always attracted and been attracted to people who have psychological problems. (One reason I decided to make one of my majors psychology.) I probably have some myself. Maybe it's because I find psychological disorders so fascinating (my field is going to be abnormal psychology) or because I understand what it's like to differ from the norm (or a little bit of both), I don't have a problem dating people who do have psychological disorders, as long as they aren't a danger to themselves or others.
But then, there was always that one that tried to run me down with his car...
