how do i help my autistic brother.

he got kicked out of his place, gf left him, spending way to much money, and a drinking addiction. and now the police have pulled him over for drinking and driving. (he's getting his vehicle impounded, which is a good thing.)

every time i've tried to help him, he literally just straight up ignores me, every single freaking time i've tried to help him he just ignores me. i'm not sure man. i don't know how to help him.

he's never gotten a charge before and now here he is getting one.

he also has a decent sum of money saved up and i'm scared for him to just drink it all away. all of that hard work just to end up drinking it all away, but the thing is, he even won't even listen to me man. i don't know what to do. our whole family keeps telling him but he just won't listen.
