Verse 1:
Well you [ E ]filled up my head with so many lies
You've [ A ]twisted my heart 'til something snapped inside
I'd [ C ]like to give it one more try[ D ]
But, my give a damn's busted[ E ]

(same E - A - C - D pattern for all other verses)

Verse 2: 
You can crawl back home, say you were wrong
Stand out in the yard and cry all night long
Go ahead and water the lawn
My give a damn's busted

Chorus: G - F# - E
I really wanna care
I wanna feel something
Let me dig a little deeper
No, sorry, nothing

E - A - C - D
You can say you've got issues
You can say you're a victim
It's all your parents' fault, I mean after all you didn't pick em
Maybe somebody else has got time to listen
My give a damn's busted

Well your therapist says it was all a mistake
A product of the Prozac and your codependent ways
So who's your enabler these days
My give a damn's busted

Chorus:
It's a desperate situation
No tellin what you'll do
If I don't forgive you, you say your life is through
Come on give me something I can use
My give a damn's busted

[Chorus:]
Well, I really wanna care
I wanna feel something
Let me dig a little deeper
No, man, sorry
Just nothing, no

You've really done it this time
My give a damn's busted
