Oh, how I wish I didn't have a heart sometimes. Being hurt, used, and broken, we tend to barricade ourselves from ever feeling that again. In my case, I do that, find someone else, let down my guard, and get hurt all over again--each time becoming a little bit tougher than the last.
I like how you ended with "I don't have one." I think we all feel that way after going through so much.
