I was severely anxious and angry as a child but that was more my circumstances than anything. I was depressed after my father died but of course I would be. I went through about a year and a half in middle school where I was very happy and loved life. Then depression hit in eighth grade and it all went downhill from there. Still, I don't think I showed bipolar tendencies until I was 18. At the time I didn't believe it because I was never happy but now I can recognize that I cycled between bone crushing depression and severe agitation, probably mixed states. After a round of ect it went away for about six years, although looking back I can remember mild mood episodes. Then it all went to hell again right before I turned 25. I'm still not sure what triggered the sudden severity.
