I am starting with - Treat her like you would any other adult.
That's an excellent start. Many times the question is asked here.."If anyone else treated you like that, would you accept it?" There is a lot of clarity in that question.
What kept me strong at the beginning of my recovery was group support, here and at live meetings, and working a 12 step program that helped me rebuild my life and whose concepts I still apply to my life today, even though my addicted son has been gone for over 10 years.
What keeps me strong today is faith, prayer and meditation and a lot of time spent in nature. Nature is where I find my peace and spiritual connection. It reminds me that life really is beautiful and uncomplicated, if I stay on the good path of recovery and peace.
Good thread, Troubledone. I hope many will respond.
