How do you know what comes next is better? What if there's reincarnation and your next life is even worse? What about hell and purgatory? What if you get stuck as a spirit in some sort in eternal torment? No one knows what comes next and how do we know we can circumvent pain just by trying to check out early? At least this life is pain, misery and suffering that I know....what if after is worse?

I've given it lots and lots of thought and I would need a guarantee there is NOTHING after because I simply don't want to exist at all anymore. BUT there's no way that anyone can guarantee that we just blip out of existence so I figure why trade one craptastic existence for another? Where's the point in that?
