Dear depression,
     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 make connections with any of my friends or 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 part of my life again. I hate you, and I hate myself for ever letting you in my head. 

Sincerely,
ME.
