Lyric discussion by andrew813 

your silver tongue it masks your hungry hate while your haggard heart whispers through its cracking cage you still can change, you have to know, you still can change I know, I know, for now I wanna be this way

haggard heart whispers through its cracking cage

I think that means that he is starting to realize that his lifestyle is wrong and that he needs help... he is starting to be able to hear what he heart is truely saying, The cage around it is cracking away.

When he says that knows that he can still change means that he knows he needs help but he is procrastinating getting help
