Voice inside my head.

I'd stab at all your invisible veins that crowd my head with vile,
Your vicious thoughts, they drain me so, make me an imbecile.
You make me cringe, those haunting words you echo in my brain,
Your voice of treachery, only adding to the pain.
Devillish whispers consume my head, torture and despair,
When there is none, I've come to know, you are always there.
The worst part of this nightmare, that might ever be,
Is that you are, undeniably, still a part of me.
You've driven me insane with everything you've said,
And you are, alas, none other than the voice inside my head.
