Uncertainty

Doubts and more doubts. Right now, there's nothing else but uncertainty. It's like I don't even own the doubts anymore. It's them who own me.
If it is actually good not to know everything, it is just as bad not to know anything. When I'm not sure about anything, I second guess every choice I made and every choice I'll have to make, the chances taken and the ones not taken. Was it worth it? Is it worth it? Or will it ever be worth it?
