Considering her background, she has several of the risk factors, and the number of symptoms, I think it's something to explore with the doctor.
If she doesn't have RAD, she sure has something close to it. I was flabbergasted reading the webpages.
Maybe I'm beating a dead horse, but I would like to exhaust every possibility before I just give up. It's not like I could feel much worse...but maybe it isn't too late to help her.
