I relate to you on this. I have always felt since I was young that I was "meant" to CTB. That I was just one of those people in the world whose path leads there. It's hard for me to imagine a life long lived.
I don't really know what I believe in as far as fate and destiny. I had a conversation once about suicide with someone close to me though. They are not religious, but they are spiritual and believe in karma and a natural flow of the universe, that everything is how it is supposed to be. They said they felt as if killing yourself was "against the will of the universe". That when people chose death, they are going against everything that is meant to be. I told him if he feels that way, that people are all on their own predetermined paths, would it not be true that possibly some folks are just naturally ingrained to go down that path? That suicide is just what fate has in store for them?
It was hard for him, but he ultimately kind of agreed that I had a point.
