I couldn't find much information regarding this. I don't know what could have triggered my viral reactivation; I believe my symptoms began around 2010. I was not under a lot of stress and it did not begin after I was ill. The only theory I have is that I had an eating disorder for a period in 2010, orthorexia to be specific. I ate 100% raw vegan for about three months but I did not do it correctly and lost a lot of weight (when I didn't need to.) I wasn't getting enough calories, as is hard on such a diet. I am a very healthy weight now and am on an omnivore diet. Is it possible that this put a lot of stress on my body and triggered my illness? Or can it just 'happen', with no direct cause?
