I see a lot of suicidal people here. Believe me, I can relate. I'm 37 this year and for half my life I've debated with myself whether life is worth living. Even now I sometimes fantasize about ending it. Life can be downright exhausting, hopeless, degrading, heartbreaking, etc. Still, somehow I keep on. Here's the things that keep me going. I hope it helps someone.
1) Revenge. Lots of people have screwed me over in life. I want to be the one to spit on their graves, not the other way around.
2) Hedonism. There are lots of sensory experiences to be had in life. I've had my fill of drugs and crazy sex, but there are still other things to experience. Being dead is a guaranteed to be boring.
3) Fear of possible afterlife/reincarnation I basically think religion sucks and most spiritual doctrines are honeysuckle, but there is always a possibility that I'm wrong. It would be my luck to off myself and go to some crappy plane of existence, or get reincarnated as a politician (shudder)
4) Power. As the truly villainous among us know, power over others is it's own reward. As long as you are alive, there is a possibility that you may become powerful, influential, famous, etc, and have the adulation of the masses. Dead people can become famous too, of course, but I am sure the rewards are minimal.
5) Impact. There is that whole "other people" thing that some of us are vaguely aware of. Unless you are a complete hermit who lives in a cave, someone is going to have to deal with the aftermath of your death. Even if it seems like no one cares, one or two people probably do. Granted, it won't be your problem after you're gone, but in those last few moments before the darkness swallows you forever, won't you feel like a total ass?[/b]
