Violent heart

I know this is a rip-off of a Good Charlotte song

This is for you
For the guy who never asked me out
This is for you.
For the boyfriend who didn't treat me right
This is for you.
Sometimes I feel so harsh inside
I want to pummel you with my fists
Its violence and anger and pain in there
and I want to fight and kick,
lash out
until you feel the pain I do.
I look so kind and innocent
And so you break the heart of me.
You break it down
just break it down.
I wanna break you down.
