Everyone will have a different idea about how to help, so I'll just say what comes to mind when I hear this.
She is deeply traumatized by the events of her youth, that much is clear.
Rather than delving into the trauma as many therapists might do, there can be steps forward into wholeness in other ways.
For example, is your daughter mineral deficient? This leads to so many things, anxieties and depression, all sorts of things, perhaps the trauma itself is locked in the body and having a hard time getting out because she is imbalanced. The best way to recover mineral balance is with a system called RBTI. Dr. Reams developed it, and there are a few practitioners scattered across the country. Try brixman.com, the yahoo! group can be contacted there, and you can locate a practitioner, within a week you can have a perfectly clear picture of where she stands mineral-wise.
I hope that this helps her.
Another useful tool is available on here, Dr. Charlie is his name, and he deals with healing the liver, which also stores a lot of anger and resentment, most health conditions start in the liver. He'll send her a liver tonic, and create a program for her, if you contact him.
EFT is emotional freedom technique, there are so many practitioners across the country that might give her help, she can do basic tapping when she feels stressed after a dream, or if she gets shaken up.
I hope some of this is helpful. There are heart-based meditation practices available, as well, one is called Sahaj Marg which has, as part of its practice, a cleaning component whereby old impressions are removed from the system.
