I understand the desire to move out, and I feel it too, my parents were always less than fair about a lot of things, but pretty soon I'll have a place of my own.
I guess my advice to you is that things will get better, they always do, no matter how bad it seems. I've struggled with Bipolar II (undiagnosed for many years, misdiagnosed as depression) and Schizophrenia, and there were times when I've wanted to die and tried to, but I'm feeling so much better now and I haven't sh'd in years and all my scars are faded, and I'm getting engaged in less than six months, it's so much better than my life was two years ago, and I'm sure you'll find that life usually works itself out with time. Hang in there
