Is there someone on a more mundane level, like a counselor that she would talk to? My wife was in a serious car-crash about 25 years ago that left her right arm (temporarily) paralyzed and left her almost blinded due to a fat embolism that caused brain damage. She's pretty much recovered now, but I used to have horrible dreams about those injuries and I wish I had consulted with someone who could have helped me work through that. For many years, I was stricken by the fear of her loss and would wake up sweating in a panic if the phone rang while I was asleep.
I hope you can help her get help. I didn't get that help.
