I think its either called "im sorry mama" or "Im cleaning out my closet"
If you get past what he presents to the world, he is really a guy who is in a lot of pain trying to stuggle out of it. He once thought about going nuts, killing himself, maybe even his wife and his daughter, to the point where he had a gun loaded. In this song, he says "The smartest thing i ever did was take the bullets out of that gun."
I dont care what people say about him, that is courage. Not giving in to those demons in your head.
