Crushing Someone You Love

I have nerve,
you don't deserve to take what I dish out or stick with me.
I'm not too bright I just lose my sight of what I strive for and want to be.
So I want you to know that I'm willing to go.
So I want you to know although I know to run,
will never be the answer.
There's nothing to say,
I just want to bury my head I shame.
No card I can play,
I fold my hand in this game.
Now it's clear your worst fear.
You're in a web and desperate to be free.
Well beyond cruel,
I'm not that jewel you thought you had discovered when you found me.
