I'm sorry that i said i'm sorry

Can I help it
that I have problems?
Should I be sorry
for messing up?
It's not my fault
that i'm not like you.
But I can't not apologize
It's just too hard

YouStupidBitch!!
I can't help it! I'm sorry!
WorthlessLittleWimp!!
It's not my fault!
YourGonnaPay!!
NO! Please! STOP!

But once again, i'm on the floor
bruised and bleeding
and a tear streaked face

Why did this happen?
What did I do?
He's right, i'm worthless!
Why did I say sorry for something i'm not?
