NN-
She definitely is blessed to have you both. I have 2 daughters and my biggest blessing is (so far) they are not addicts, DD21 & DD23. They have their fathers DNA and I informed them when they were old enough to understand that they were predisposed. They younger they start experimenting the harder it is to pull them away. Keep your fingers crossed and pray, that's all you can do.
Hugs to you, she has a fighting chance in this world!!!
