@Keller, welcome. I hope you have taken the time to read the CoC
I am really sorry about your friend. She sounds like she has had a really rough life so far.
Do you want to help her, or do you want to fix her? You can't fix her life, you can't erase what happened. You can be a good friend, however. You can help her by listening to her. You can help her by not trying to control her behavior or her reactions to what she has experienced. Both cutting and anorexia are attempts at controlling what feels like an out of control life. Believe it or not, many attempts to help can feel like attempts to control, and can reinforce such behaviors. Be honest with her, but non judgmental and extremely gently. Tell her she doesn't deserve what has happened to her. Tell her she deserves to heal. Tell her that you understand why she does what she does but it scares you and makes you sad because you care about her.RAINN
is probably the best group I can think of that may be able to help her start to process what she has been through in a more healthy manner. She has been through a lot and may never get to a place where she feels completely "normal" (do any of us?), but many people survive very traumatic experiences and have fulfilling lives. It may be very difficult for her to see a long, possible future ahead of her, but it is within her reach.
