I'm not a parent of addicts, but all my siblings are/were addicts (I'm the oldest of four). The sibling next to me, my sister, has now been sober 4 years (I've been sober over 9). My brother, the youngest, walks his own path; i'd say it's harm reduction and works for him. My other sister, however, the third child, just passed away last year from her addiction. It's taken a toll on the whole family, my parents and all of us siblings. It's impossible to face the heartbreak of watching someone self-destruct and not be able to help them. In my case it was even more baffling because i'd been there myself and i thought that would somehow enable me with special powers to help her, but it didn't.

I agree with FireIsland123. There's not really anything you can do for him. He has to want to help himself. I would maybe just connect with people with shared/similar experiences, people who can help you come to terms with your own grief and loss and strengthen your own life. Something that was said to me so many times in the first years of sobriety as I watched the destruction and chaos that addiction was wreaking in my family was 'sometimes you have to be able to let go and love them from afar.' it sucks in the biggest way but it's true. sometimes it just comes to the point where it's either let go, or go down with them. i sincerely wish you all the best, my heart goes out to you and you are in my thoughts. if you ever want to talk about it with anyone on here, you can always PM me. Take good care.
