“ Soon madness has worn you down. It’s easier to do what it says than argue. In this way, it takes over your mind. You no longer know where it ends and you begin. You believe anything it says. You do what it tells you, no matter how extreme or absurd. If it says you’re worthless, you agree. You plead for it to stop. You promise to behave. You are on your knees before it, and it laughs. ”
