You can guide her to the help she needs and if she does not except that than there is no more that you can do. It is hard when they have no one else or so it seems but just like it is up to us to seek the help or except the help if we need it, so it is for her. That is so hard but I know I got to the point where enough was enough.
I know every time I was at my total bottom I would except any help given and when my friends could not do that then I knew it was time to give them up or loose me. Selfish? maybe but I am alive and so are they. We may not be that close now but that is the way it has to be.
It is not easy to let someone go to find their way but some times it is the best. Some times we just need to let go so they can travel the path they need to travel.
