Mono 3 times? Diagnosed with mono 3 times in 2 years? - low ferretin only at 3

He did not even know who has ever had. I have a low ferritin level. In the store fainted and was transported to the hospital just told me I had mono again. I have abdominal pain, vomiting and dizziness to each position. I'm tired and I feel that I can not breathe. Is there someone who has experience with this or know anything about it have?
