I strongly suggest just working on you. Keep your sobriety a focus. You will change and be an example.
My friend is in AA and her daughter is not. Her daughter, 27, is in a bad way. There is nothing my friend can do right now except pray, keep herself sober and reach out to others. Not until her daughter wants recovery, nothing will change. It is difficult for her to watch.
Pray on it and keep yourself sober.
With much love and big hugs,
