@RiverX - Of course I'd like to avoid hurting people. Especially in my current situation with this ex-friend, because she's not taking it well. However, at this point I think it's likely that SHE's the one with some sort of disorder...
There's actually not much negativity in my life. Maybe a better word would be stress. I did fall behind in school not too long ago, and sometimes social problems can be a distraction. Plus, I'm starting a job hunt tomorrow, and on top of that, I'm too concerned with other friendships to be worrying about her inability to let go. My friend's birthday is tomorrow. We got him a Wii.

Since she's been "playing the victim," asking how I could do this to her, and claiming I'm heartless, everyone has lost sight of the fact that I was the one who was hurt in the first place. I lost a friend, too. But for a while I couldn't tell if I'm not affected by this loss because I'm overly insensitive, or because she's been harassing me nonstop and I'm glad I cut it off. I'm pretty sure I'm just happy not to deal with her anymore.

@Rapunzel, nice post. I had a few diagnoses as a kid, such as depression, but during adolescence it went away save for a bad case of PMS/PMDD. Now, we've just about completely eliminated all of my depression symptoms. My tendency towards independence has still followed me all through my life, and it puzzles people, but only in certain cases does it hurt them. Looking back, though, these friends are, ehrm, quirkier than I am.

@Junerain, I'm thinking that my independence is mostly just a shock to people. I have a good understanding of social situations, I get along with lots of people, and my friends even say I'm "obnoxiously polite" in dealings with servers at restaurants or sales associates.

I think I'm getting it now. I don't think I'm schizoid. I think I'm independent, but that trait is in pretty big contrast to my other traits, and to the way people see me.
