Used to be.

I'm a mess right now
And I know you don't care
It makes no difference at all

I used to be the center of your world
Now I'm a center of nothing

Your silence is a knife plunge in my heart
With every inch deep killing me
Blood drips, tears shed
I wasn't even worth an explanation

I know I'm down
And you can't see
You've turned deaf to all my plea

I used to be your everything
Now I have to settle for nothing.
