Bipolar Hell

My brother is really bad bipolar and he has tried to commit suicide before. He was fine before going away to college but he had a breakdown there and for the last few years it has been really up and down and difficult for my parents. Right now my parents are forcing him to take his medications and to see his doctors. They practically force feed him sometimes. 

He keeps saying the meds aren't helping and that his doctors won't listen . He is stable now but not happy and not his old self. Our house is like a jail and he is the prisoner. Maybe I should be happy that it is not like it was when it was bad but I just want him back like he used to be. My parents say he isn't really able to make good decisions right now but I think they are so scared of him trying to kill himself again that they will do anything to prevent that and that his being happy is way down on the list compared to that no matter how medicated up and miserable he is. It is so screwed up that he can't just be like he was before anymore. He asked me last night if he should leave home and I said of course not. But now that I have slept on it and tossed and turned all night I feel like what he has now is not quality of life. I am 17 and my brother is 22. He is an adult but no one really seems to count his opinion since he is the 'crazy' one. No one values my opinion either. I want to help him but I don't know what to do? He probably can't work and be on his own but what he has here is not good either. Is there somewhere someone like my brother can go to have a better quality of life?
