How do you have peace in an EXTREMELY over dramatic family?

I feel so bad for you. I can relate entirely to what you're saying. I've have been dealing with my backstabbing dysfunctional dramatic family my whole life and I'm 29. Nobody really sticks together in those types of family's. The most crazy ones in my family moved away. Try not to let them control your emotions. The more you gain control over that, the more they realize that you don't care anymore and they'll take you off the radar as prey.
