NA meetings could be a huge help! The members of NA are all so welcoming and truly care for other members. It could be a good place for her to vent to other addicts. I'm 26 and it has worked for me. Also, someone I know has taken a Vivitrol shot with great success, this may be something to speak with you doctor about. I haven't heard many good stories with methadone because I've heard it's very addictive. But different things works better for different people. Anyway, NA is free and they have meetings eveywhere. Give it a shot it has worked wonders for me in the past 91 days!
