If you watch the video of Fluge talking about his research studies, he says at some point that he believes that ME/CFS is reversible (curable or very treatable)---meaning that it will prove to be so, following up the line of research he and others are pursuing. So that is very hopeful.
On the other hand, my impression is that the recovery rate is less than 10%. My own view actually is that it is 0% for those who meet the Canadian criteria. But no one knows for sure. I have heard two of our long time experts, Dr. Komaroff and Dr. Bell, both say in video interviews that none of their patients ever fully recovered. But each said that some have improved a lot in terms of being able to have a fuller life, but on closer inspection, this is due to careful pacing, medications, and other self care measures. In fact, Dr. Bell said that some of these patients even regard themselves as recovered, but he has seen that if they overexerted themselves, they would again relapse.
For you and all of us frankly, learning all we can how to manage our illnesses as well as we can will help, and maybe a great deal. Then watching the latest research for when a real scientific breakthrough does come--while hopefully avoiding the pursuits of disappointing fads and miracle cures, which greatly abound, because those can pitch us into despair too.
Objectively I do think there is more hope now than ever before because of the good research that is finally happening. Meanwhile reel back your focus to one day at a time and to the priorities you can set, while knowing that when you can reach out, there are other people here willing to share their experience, knowledge and caring with you.
