EBV/HHV-6 reactivation

here are my symptoms for the last 5 years,
had bad mono at 19, Im 55

Its cycling, thats whats confusing, never know WHEN, but its always starts and ends the same. Been a long 5 years

june
2020 deathly sick, was in bed for 3 days, unable to use phone, no food, very little water, got up to use bathroom a couple times, delirious, couldnt focus enough to call or message anyone. completely soaking sheets even with very little fever. Hot and freezing at same time, while sweating.
Not the same as hot flashes. bad restless leg and MAJOR depression doom and gloom. extreme fatigue/sleepy horrible sore throat. as I was coming out of it, ended with 2 days of diarrhea and thrush like symptoms.
got the same again 2 weeks later, almost as bad then 2 weeks again, not quite as bad. ER,
end of August 2020? nothing showed with covid test... said maybe hormones,
get it every couple weeks to a month since.

I usually know its coming, by the restless leg, Nothing like first time, but starts same, out of the blue.. restless legs, cold sweats, horrible doom and gloom depression, and ends with 2 days diarrhea and my tongue has never been right since. Gets inflamed with a lot of foods symptoms never change, same thing every time.

had positive blood test for covid/ long covid?, but this doesnt really fit that either. so put symptoms into chatgpt and it said check EBV since I had a bad case. Do my symptoms cycling fit with anyone? Thanks for reading!
