In the end, people have to solve their own problems. That being said, it helps to know friends and family are on your side. That they believe in your strength to overcome. I think the best way to help her, and yourself, is to be a friend, as much of one as she can respond to. Be loving, encouraging, be subtle with it, and be warmth, be kindness, a whisper of care with nary a demand for attention. There may be more to the two of you, there may be not, but as I see it, your best intention would be for friendship either way.
