Not Perfect

I'm sorry I wasn't perfect.
I know I was incorrect.
What did I do wrong?
Why can't I belong?
I should just run away.
Why should I stay?
I should go.
I feel so below.
I'm never gonna be her.
It really is a blur.
I'm done with you.
You make me feel so blue.
You don't deserve me.
This is how it has to be.
