Trust?

"There is nothing more dreadful than the habit of doubt. Doubt separates people. It is a poison that disintegrates friendships and breaks up pleasant relations. It is a thorn that irritates and hurts; it is a sword that kills."

It's true but thats what happening to me now. I wanted to trust but somehow there's something blocking me and makes me doubtful about it. Should I trust..or should I just keep on being doubtful about it..I clueless. Don't ask me ragarding what because I'm not gonna tell about what. Kinda personal to me >.<

Anyway, I don't like this feeling at all and hopefully it fades quickly..Oh God!
Please..make me undoubtful about it...thank you.
