Ultimately, only she can save herself. But as a valued friend, you could sit down with and say something to the effect, I really appreciate all you did to help me get my life in order, to find sobriety. I get the sense that you are slipping away as a friend. Is there any way I can return the favor you gave me, and help you get back sober? I don't want to see anything happen to you. I know it's your choice, your life. But I just want to know I'm concerned. No judgment. Just concern. And I'm willing to help if you'll accept it.
