I'm sorry to hear about yoru friend, Red. As for how you can help her. You could mention to her since she still believes in the wt religion. That even the Bible speaks of God not putting more burden on her that she can bare and that he gives a helper. (Well it's something to that effect) Tell her that she can consider you the helper and that you will stand by her though all she is going though and that you will never shun her.
Knowing you are there for her will be a great deal of help to her i'm sure.
