She says she did it all to make me realize I don't love her

Wanna know what it did?
Made me give up on trying to be better.
She made me give up.
I was getting better for her.
Now, if she's going to randomly do that, I give up.
I'm going to not eat, going to carve words into my wrist, going to do what I want.
I hope she understands that.
