I'm so sorry sweetie. I know what you're going thru, because I'm going thru the same thing with my son. He just keeps on drinking, regardless of what he's doing to himself or anyone else. Then he wonders why people don't want to talk to him when he's drunk. DUH.
I LOVE my son - but I don't like him at times. If he truly wanted to stop, I'd do anything I had to do to help him. But he openly admits that he doesn't want to stop. So there's just nothing I can do about it, but watch him kill himself. I don't want to bury my son. Just like YOU don't want to bury you brother. But I've come to the conclusion that that's probably going to happen. I can't say I'm prepared for it - but I won't be surprised.
There are such people, as AA has taught us, that simply cannot or will not give themselves to this simple program of AA. My son is one of them. He's been to AA and rejects it. There's nothing more I can do.
So I know what you're going thru Fowki. And I'm truly sorry.

If you ever want to talk or vent - let me know. God bless. Hugs, Lee
