One psychologist mentioned I had Avoidant Personality Disorder (I know I have some form of social phobia, really all I need to know since I don't care about diagnostics anymore), so... guess this might apply to me.
I've had a run-in with suicide around a year ago, during a heavy depression, and often considered it throughout middle school and high school. Depression is co-morbid with many other conditions (AvPD and Social Anxiety aren't exceptions, understandably), and is associated with suicide.
Meh, I still get the thoughts from time to time. More or less, it's actually along the lines of: "I don't like living like this." I heard a while ago that most people that want to die don't really want to die. They just want out of the current mess they're in, which to them doesn't seem will ever go away. That's kind of this. I hate my life right now, and it's hard to consider it'll get better. Since I'm not convinced it'll get better, nor do I know how, I still don't want to die necessarily. Rather, I'd instead like to just sleep for a few years, "wake me up when it gets better."
I know that's not the thing to do, but as for actually getting better... I'll get back to you on that when I figure it out.
As for saying that suicide is selfish, I'm not sure it's completely fair to say it's only a selfish act. When someone is so clinically depressed, all that's on their mind is death and getting away from life. They're not trying to hurt those who love them; the contrary, many who commit suicide are convinced that those who love them would be better off without them. Suicide's just irrational like that.
