I am the one

Have you ever heard of me?
I am the one who haunts you in your sleep.
I am the one that killed your counting sheep.
I am the one that everyone fears.
I am the one that causes you tears.
Do you know me now?
I am the one that hurts you when you're down.
I am the one that pushes you around.
I am the one that calls out your name.,
And will never let you be right again.
Do you remember me now?
I am your pain.
I am the face in the rain.
I am your cries,
When you want to die.
