I can't do this anymore (RANT)

I can't stand my family anymore, I can't stand my mother , my sisters. They just make my life hard and if I wasn't scared of dying I would've just ended my life already . I went to therapy and i got better I really did, but if Iam at the same house as them I can't really escape the hell they put me through. My mother is a narcissist that I CANNOT STAND, my sisters wants every fucking thing in my life discussed with them and when I don't do that I'm the fucking vilain. The only thing keeping me sane is my fiancé who absolutely loves me and respects me unlike them. I just want to marry him and cut them the F*** off especially my mother. I don't feel like they're my family anymore and I'm drifting off more and more every day and I can't control it, I feel like a villain but i know I'm in the right..
