I don't fear death but.. Here's what keeps me from killing myself:
1) I have a HORRIBLE fear of blood or anything scientifically to do with the body. This has more so kept me from cutting myself. Rubberbands :3
2) Though agnostic, suicide is considered as a horrible sin in the Christian religion, which I was raised in.
3) After going through so much, I feel that killing myself would be like saying "okay, I've given up." And even though I feel so god damn down sometimes, giving up after ALL OF THIS just seems...almost stupid.
4) I don't think I'm going to live that long anyway.
5) I'm an empathetic person. I've seen that people tend to, ah, deal rather poorly with death. I tend to deal with it better. I know there are people out there who do care for me, and I couldn't stand to bring any pain to them. I feel that I've already caused enough misery.
6) It would be selfish. To put the end of my pain to henceforth cause pain to everyone around me.
There's probably more, but yeah...
