Go on and cry, but you won't change my mind
Your pain and troubles don't concern me
I gave you my love, but it was not enough
I was just your bridge and girl you burned me

(Chorus)
So don't hand me no hard luck story
Hopin' I'll just fall apart
Remember you're the one who left me
With nohin' but this cast iron heart

There was a time my heart was good and kind
There was no end to what I'd give you
But now I've changed, my world's been rearranged
I've tried but I just can't forgive you

(Repeat chorus)

A cast iron heart, it can show no mercy
A cast iron heart, it can feel no pain
So don't come to me for love or sympathy
'Cause there ain't none in this cast iron heart

(Repeat chorus)

Cast iron heart
