I interpret alcohol or drug abuse is this song. Especially in the second verse and bridge. Someone has become consumed by an addiction and they are now scared of the world. The addiction has left them ashamed and weak. So weak that they have absolutely no self confidence and they know that anyone could, "Eat their kind for breakfast". "...A starting place, and nothing's ever been so hard" - Trying to break an addiction.
