.I think you still love me, and now you can admit me, 'cause i've lost it.

It makes you like a Zombie.

And everyone hears you wailing and watches as you stagger towards them; instead of moaning about brains, you saying "Paaaiiiin, Paiiiiinnn"

And they all run. There you are left alone, limbering after them, repeating your empty moans of "paiin, pain".

You don't know what you're doing anymore, you don't know anything. You're a zombie, an animated corpse, the appearance of who you use to be with nothing behind your eyes except the knowledge of "Pain, pain"
