I would mention the wide range of diseases that can cause ME/CFS - starting with EBV/glandular fever, because many people know people who took a long time to recover after glandular fever, mentioning Ebola, Ross River fever, Q fever, and Covid-19.nI would note that there is no evidence that any sort of personality type or psychological history increases the risk of having ME/CFS.
I would note that many people recover in the first few years, and that can lead them and other to thinking that there are cures, when actually it is just what they were trying when they recovered naturally.
I would mention the different levels of severity, and how it can be a living death, people can be fully bed bound, requiring 24/7 care.
And I'd talk about the scientific recipe that can "prove" almost anything helps - subjective outcomes coupled with unblinded treatments that discourage people from thinking and saying that they are ill. And that that recipe has been applied to all sorts of suggested cures for ME/CFS, but nothing has been credibly proven to cure ME/CFS. I'd mention that there are now many more researchers working to understand the biological cause of the disease, mostly as a result of so many people getting it after Covid-19 and the dawning recognition that the disease has a substantial economic impact.
That's a pretty long message of course, and there are lots of other things that could be said.
