My issues cannot be quantified.
My first time talking to a therapist in four-ish years went down a few days ago, and long story short, she couldn't figure out what's wrong with me. I told her why I suspected ADD, I told her my history with depression, and I guess some of the things I said pinged 'anxiety disorder' to her. So the purpose of the testing is to figure out what the root of it all is, which might wind up being one of several things or a combination thereof.
I'm actually kind of looking forward to it. I've never been tested before, my first therapist just said 'yep, sounds like depression, here's some pills' and I guess subsequent therapists just took their cue from that. I'm kind of curious about the whole process and what I'll find out about myself. Who knows, maybe I'll have some obscure and freakish brain chemical imbalance unknown to science. XD
(I have to admit I'm kind of married to the idea of ADD though. It really does seem to fit, looking back on my history, especially at school. There's a definite attraction to the idea that I could take a pill and become less useless. ...though I know it's not going to be that simple.)
