Girls, What is the best way to turn off a crazy girlfriend?

Mistawasis
I found out that there is something wrong with her, a week into the relationship. She is super obsessive and very emotionally unstable. I won't go in details here, but let's just say that she is very prone to dangering her own life and/or others when she is upset.

If I initiate break up with her, she will definitely go insane, and I'm worried for my life. So I'm thinking of turning her off and make her break up with me instead. I want to make her feel disgusted of me and stay away from me.

I need some input from the girls. What would turn you off from a guy you like? Not including things that might provoke anger such as flirting with other girls, cheating, etc.
