You need to leave me alone already. Everyday you're screaming at me and telling me how terrible I am. You make me replay every mistake I've ever made. And you humiliate me on a daily basis.
You've made it impossible for me to be happy. Or have any connection with my friends and family. I am so sick of you controlling me.
The sooner you leave, the better off I will be. Don't come back, either! I never want you to be a part of my life again. I hate you, and I hate myself for ever letting you in my head.
Sincerely,
Me
