As I was reading this I too thought, MONO! Right off the bat. I had it when I was a senior also on top of Strep (yes, strep and mono at the same time and they ARE two different treatments - NOT FUN!!! and then on top of it got a bladder infection). I am so glad you took her to another place and they treated her. It took me a very long time (years) to recover from my mono because my immune system got hit really bad after having severe pneumonia several years in a row. Still, to this day, takes me a very long time to get "unsick" and I almost always have to go to the doc and get meds. I don't get a cold, I go right into bronchitis or sinusitis. I so feel for her - tell to always take care of herself, wish someone would have told me that!!!!
