I'm glad you asked. I inherited, from my mother, a sort of mood cycle. I'll go for a few months being depressed. Then I'll go for a few months seeking companionship and searching for the meaning in things. Then, for a few months, I'll be happy but distant. I've probably got about 12 different and distinct moods. They stay constant for a few months and then, BAM! It switches directions almost overnight.
My mom is the same way. I would be smoking pot with her one part of the year while 4 months later I'd be locked out of the house while she is burning my cassette tapes at church.
I haven't gone through a deep depression cycle since I've been taking anti-depressants. That's good. Most of the other moods I can handle. The one coming up is Anger/Hatred. This is where I get mad enough at myself for being lazy or otherwise below expectation, and mad enough at other people for not helping me that I do something about it. Mostly, this is good. I usually get alot done and I can usually maintain an exercise regimen. The only downside is that I get a bit snippy and I sometimes let my contempt interfere with work. Hopefully, since I'm on the Gleemonex, it won't be as intense as it usually is.
