My brother is really scary and causes stress

My brother has mental illness and he takes out all his anger onto the family. He’s only 17 but smokes and drinks and on top of that has severe depression and Asperger’s. Every single day he’s yelling, slamming doors, doing things to purposely tick people off and he doesn’t even care about it affecting us. Infact, it seems like he’s trying to affect us negatively. I live in the same house as him because I’m a minor too and there’s nothing I can do. I can’t even stay at a relatives house or anything because they live far away and I have school. Basically, everything he does causes me severe anxiety and stress because he says he’s gonna kill himself, he slams doors extremely hard, he stomps hardly whenever he walks, and yells at everyone like I said. He does even more terrible things but you already get what I’m trying to say. So, please give any advice if possible and thank you so much.
