I'm the vampire that lives inside

You thought you could save me.
From this place you call hell.
Well you can't.
Because I'm part of it now.
I'm the vampire that lives.
Inside of me there is no more of my old self.
You can't save me.
Because I don't want to be saved.
I want to be the creature I've become.
I don't want to go back to my old ways.
Not even for the one I love.
I'm here to stay and there's nothing you can do about it.
I'm the vampire that lives inside.
