You have a lot more options than you think. Personally I would not suggest you help those that are unwilling to help themselves. Instead if you have to help someone help the one that can't help themselves, like your brother. Move out, get work, join the military, or whatever you want but get away from your parents. But keep on eye on your brother. Refer him to social services if you have to in order to make sure his needs are met. If your parents aren't willing to step up and take care of him then when you get settled have him move in with you. That will be really hard on you so don't do it until you are settled. If his life is in danger at home and you aren't ready to bring him to you, then don't be afraid to report on your parents. They have made their choices, and it sounds like you have talked to them about changing things. If they refuse to get the help they need, then don't waste energy trying to help them. There are programs out there for your brother. But you wont be any good to him if you can't take care of yourself. Good Luck.
