Since you wrote in this post and prior posts that it has been five years since your daughter has stopped taking cortisone even though she stress doses this is way more than just take the med. because she has been not taking it for five years now. But the one positive here is that you wrote that she does stress dose which is positive.

Good luck with all this and really isn’t easy. I would bet something happened at 15 to make her stop the cortisone because what was done to me at age 11 - it was very easy to just go nope stop the pred and looking back it was fine for six months but not really as it was feeling like low grade sick all the time but it didn’t bother me becasue I felt better to aagain not really but it did seem like it and I kept to a quiet time of watching TV  but after a couple of months felt so worn down and then the vomiting. I remember beening happy to tell the big people at that hospital that yep I don’t that that stuff anymore and ergo in my mind the doc and his students then would have no need to touch me.

Is she going to school?
