This is, sorta, how it feels to have voices in your head. Or at least how I feel. It’s overpowering like you have lost complete control of yourself. Just try to imagine. I think of it like a Demon that tells you the most harsh and vile things of the world. Trying his best to break you. 
They come at your most weak and vulnerable times. Pushing you further and further toward the edge. There is no escaping them. They have no volume button. You are in their control, and they are sounding more and more enticing as you break. The psychosis setting in, if you will.
Sometimes when you are really at your worst, flashes of blood appears. Blood drips from the walls and light fixtures. It comes with an inability of satisfy the urge to see blood. The only control you have is your self. You can’t loose it, even for a second or it takes control. You are your own worst enemy.
In the end, all I can say is schizophrenia sucks!
