You kill me

Oh God, please don't tell me this has been in vain....
I need answers for what all the waiting I've done means.
I know what I should do, but I just can't turn away!
I loved you, and I should have said it
But tell me just what has it ever meant...

I can't help it baby, this is who I am.
Sorry, but I can't just go turn off how I feel.
You kill me, you build me up, but just to watch me break.
I know what I should do, but ¡ I just can't walk away ! .
