I'm sure many folks tried to step up and help her, but it ain't easy. I've known folks who are addicts and they will just avoid you if you try too hard to stop them. They will just go to people where they feel more "accepted" if you tell them they are on the wrong path and try to step in. Then at that point, you're just out of the picture and you can't help at all. You gotta try to find a balance between being trusted and helping but that can take a very long time and before you know it, it's too late.
