I Think My Mononucleosis Weakened My Immune System

I had a bad mononucleosis for 2 weeks back in 2008/09. I was a very healthy person before that. After I had mono, I've been getting sick a lot, i was either having colds, fevers, then 3 or 4 ear infections since then, which I believe were the reason I got my tinnitus, my doctor suspects the same.

I'm trying to wrap my head around how one disease can have such a huge effect on my body in the long run. Crazy. But anyways, my T episode day is on today, gonna listen to a lot of stuff during the day it seems, oh well.

Have a nice day, everyone
