Darling you are a great friend. The best thing to do is listen abd encourage healing. Her shrink will help her but she still needs her pals to be there for her to vent to. I remember watching my friend stare at a sandwich with this hateful stare. She lost her period for years but is healthy now. It took work with professionals. Just hold her hand when she cries and tell her you are there for her. That means more then you know to her.
