Welcome to SR. I, too, am the mother of an active 26 yr old addict daughter, who now has a 20 month old daughter of her own.
I agree with those ahead of me. Have faith and hope but don't allow her addictive behavior to control YOU. You need to keep yourself in recovery or you will become as sick or sicker than she.
You have found a great place. For me, it was and is my sanity!
