I remembered seeing something my doctor wrote

A few years ago I was very ill the cause was Epstein-barr. I remembered seeing a note written by my doctor saying something about there possibly being something going on with my bone marrow. It said something about auto immune/bone marrow?

I never followed up with it or asked about it but I do wonder. Maybe it explains my fatigue or easy bruising. I wake up with random bruises maybe it's related somehow. Maybe I'm completely off base and crazy.
