I actually can relate a lot to that.

My main worry is that my actions will get worse as I get older, if I actually do have a problem. Right now, I can mostly manage my moods by working out and eating better. However, it also just puts me in one of those really high moods. It makes me feel rather, not fully (proud to say I can still sometimes maintain a sense of logic when it comes to this), invinicible. I do a lot of stupid ****, I fight with a lot of people - because we ALL know I'm the only one that can be right -.-

Granted, I've never been to therapy, but I get the same with jobs. If I don't get a call for an interview it sends me down the same spiral, and they've never even met me! It's like "even on paper I'm not good enough for anything" etc. etc.

And, yeah, there are always reasons. I have rather good intrapersonal skills, or so I've been told. I can usually look within and figure out why I do what I do, if I sit around long enough to think about it, anyways.
