I'm afraid.

I'm afraid to miss anything beautiful.
I'm afraid no one will remember me.
I'm afraid I'm just not that important.
I'm afraid what I want to do is just plainly pointless.
I'm afraid there's too much pain to take.
I'm afraid my friends will be sad although I don't think my disappearance will make any difference.
I'm afraid he won't learn to live and go on with his life.
I'm afraid I'm too sinned to leave so early.
I'm afraid God won't forgive me.
I'm afraid of the life after death.
I'm afraid, I really am, now I'm stuck in the middle, I can't leave or stay, for I have no value.
