Do you become depressed after your highs? I usually do which is why I can't allow myself to enjoy it. I always liked my highs and never believed there was a reason to worry. Unfortunately my highs turn manic. For me, once the mania ends I plummet into depression. I tend to have mixed episodes so I am diligent of my moods. Although I like being happy and having energy, it is risky because those pesky thoughts of suicide pop up and sometimes it sounds like a very good idea. It sounds like you experienced that yourself.

I guess it all comes down to consequences. How much do your highs 'cost' you and does that bother you? As far as recognizing it, I suppose charting your emotions could help.
