...I feel peace in the summer cabin b/c I don't have to walk on eggshells around my daughter.
Ahhh, sweetie, I learned with my son that walking on eggshells didn't help him one bid and it sure made me nervous. She will get clean or not get clean whether you do this or not, nothing we do will change that. If love could save our addicts, not one of us would be here.
Live your life as you want, live in your home or your cabin and visit or invite anyone you want. Don't give up your life for her, you may wake up like I did and years will have passed and nothing may have changed except you are older and sicker and tired.
What helped me regain my balance and my life was meetings. Al-anon, Nar-anon and CoDA have helped many of us here. It's worth a try, I think you may find it a comforting way to live a healthier life.
Whatever unfolds, please take care of yourself first...and get rid of those dang eggshells, they hurt our feet.
Hugs
