17 with one supporting parent moving out in cali?

Would you move out?

I am 17 and graduating this year. Both my parents have been physically and mentally abusive to me & lil bro and CPS (child protective services) had to get involved. I have a huge health issue and hopefully by fall when I start school I'll know what it is and what to do. I am sick and tired of dealing with my parents inability to communicate! No matter how much things go south they never get any help anymore. I am totally aware this is not my situation to deal with but I am effected by this to much to want to stay any longer than late summer/early fall. I have a serious relationship with a boyfriend who drove cross country to live close to me. We are considering moving in together. I will have health/denta/vision insurance plus financial aid for school as long as I am full time student when I'm 18. My mom is supportive of this decision if I do do it. I love both my parents a lot but I feel I'd benefit emotionally and possibly physically by leaving the house. My sucky health issues and school and what left I have of a life is enough. PLUS basically everyone in my family has run away before they were 18 in their life most succeeded we all love each other etc.

I talk to them about how they effect me but they refuse to grow up and deal with their situation.

Parents need to grow up sometimes -_-;

So would you?

yes, and I agree with Tylersn. have a back up plan.

you dont say how old your brother is, can you make your own place if you decide to go ahead with it as somewhere he can visit if it all gets to much for him back at your parents house

like you say your parents are old enough to sort themselves out, but your brother needs your love and support
