rabbit_hockey_ that is a tough one. Looking back on the way I was before I was diagnosed I must admit I was a bit disappointed in my parents and close friends for not speaking up and telling me to get help. My mom has been diagnosed since I was kid and she is treated.

How you get someone to get their own help. That does need to be their choice unless they are a danger to themselves or others, but in saying that I couldn't sit back and not say anything to a friend or family member.

Your one line in your post "I would like some advice on how to approach her and tell her I'm there for her". I think just saying those words to her may help. You may get a very defensive response, but that doesn't mean it won't get her thinking.
