@Gingergrrl, gosh, unusual to meet EBV so late in life! In my reading about EBV, there's an idea repeated often that the older you are when you first encounter it, the more severe your illness will be, and the greater the likelihood of complications. Childhood encounters are mostly asymptomatic, in fact. In the developing world most young kids are EBV positive, suggesting much earlier contact than in the West. Observations like this are given as support for the "hygiene hypothesis", which is essentially that we shouldn't try to avoid contact with viruses that are endemic, but rather, expose ourselves to them as early in life as possible. A new EBV vaccine is being developed, which might work in a similar way to early exposure but without the risks. If successful, it might save future people from the complications of adult EBV infection that some of us have suffered.
Its interesting that you had another severe, mysterious infection not long before the "doozy". A few other people, including
@heapsreal, have reported a similar thing (I think his was the other way round, mono THEN chickenpox?).
That's right: my totally non-functional period lasted 2-3 years. Mine is a very relapsing-remitting type of MECFS, and the relapses just got shorter over time. In the first 2-3 years, each often lasted well over two months with only small breaks between. By year 4 (1994), the worst relapses were now only 2-3 weeks, and well separated, I could work fulltime again. The next 6 years were even better, even fewer, shorter episodes and long remissions. Almost normal, really. In the early 2000s, I had kids, which led to a setback, so things now more like in 1994, but still way, way better than the first 3 years.
I lecture in cognitive neuroscience/neuropsychology. So no medical expert, but the experience in reading papers and understanding arguments helps. But instead of the broad knowledge a doctor has, I just have a few islands in an otherwise dark sea of ignorance!
Definitely, take it easy when you feel crap, but don't beat yourself up because you didn't in the past. Maybe that impacted on your health, maybe it didn't, who knows? We're not to blame; we only do what normal people have done for years, and gotten away with!
Here's hoping you see some better health in the next 12 months!
