My suggestions? Find Naranon or Alanon meetings in your area and start attending on a regular basis. My parents never sought any recovery for themselves despite all the damage I did and it's painful to this day. We have a good relationship, but it's limited just because of that.
Get the book "Codependent No More" by Melody Beattie if you haven't read it yet.
Educate yourself on addiction as much as possible.
Not only am I a long-term recovering addict, I also have a 33-year-old daughter in active addiction.
I love her from a distance. I allow her the dignity to live her life as she sees fit, regardless of how dysfunctional that may be.
I had to go through every miserable experience I had in order to hit a bottom. I will not rob her of her right to hit a bottom.
I sleep well at night knowing I have placed her in God's loving hands.
Sending you hugs of support!
