Insanity problem

I've been living in a small apartment for over four months now. Only a few weeks ago this gorgeous woman with huge tits moved into an apartment afew doors down from mine. Believe me guys she has an astounding body structure, DDD+ cup tits and a face that a man would kill for. Suprisingly she got rather friendly with me right away. At first I figured she was attempting to do some gold mining in my wallet, but after time I found out differently. She came from out of state to attend a college near the apartment complex (because it was the closest one that would give here a scholarship), unlike me who works part time at a used car dealer and sits on my lazy ass in the freetime. Anywho here's my problem. Recently I've been having dreams where I storm her apartment and brutaly rape her. As in brutal I mean stripping her down, fucking her in the ass and/or pussy and cutting her tits with a large knife. It's gotten to the point where I can't be around her without thinking these thoughts. I don't answer her calls anymore or drive her to school because I'm to afraid I'll lose control of myself.

So am I insane? What Should I do? Seriously, I need help guys!

Do it. You'll feel better, trust me.
Just make sure you no one finds out.
