Who are you

I am a puzzle that has broken pieces.
My puzzle is complicated.
It has a certain mystery about it.
Sorrow and pain flow deep beneath my soul.
I cry tears that don't belong to me.
I throw fists that have no meaning.
Can you feel the emptiness of my heart?
My heart does not pump blood through my body.
Instead it gets hurt by OOMPA LOOMPAS!
I wish everyone could start all over.
I am Kuwanda.
