Awful. In the first years I often felt like I was well on the way to getting better, only to relapse again.
At least the relapsing-remitting course will be captured. But it really sucks that it has to happen while we are watching it happen and no one pays attention to what we are saying because it's negative to point out bad things. Yes, it's gloomy. But, no, it doesn't change the facts, let alone outcomes, to be "scared" of something bad. It will happen no matter what and in fact being aware and prepared for it is how to minimize harm, if only that were a thing people were concerned about.
This is becoming a pretty dominant theme in the long haulers forums, people relapsing months after. Same on Twitter, including from some of the more defiant ME doubters. It's interesting to see the patterns, though. This kind of fluctuations happen early and through the course of the illness, some people feel better for days and then it comes back. But now the same is happening with longer cycles. There is so much information underneath this but no one is paying attention to it, only the surface, no depth.
I had 3 significant remissions. The 2nd one was the closest to a full, something like 85% back for almost 2 years. All this is stuff we know from personal experience but no one has ever recorded it in a way that can be analyzed, even in hindsight. Everything's been shredded and burned to ashes, the information may as well have fallen into a black hole. We can't even show this is the case for ME because no one has ever done the kind of in-depth study that can accomplish this. What a waste of millions of human lives.
A system unable to learn from mistakes is guaranteed to repeat them over and over again. And that system is very angry that people keep pointing out the mistakes. Lots of huffing and puffing ahead about how this is scaremongering, even though it is actually severely underplayed because everyone seems to assume it will magically resolve itself with time. It worked with us, after all. Problem resolved, many people do say. They don't hear about us anymore, they say. This was a fad back then, but it isn't now. Out of sight, out of mind.
