My impression from listening to Jonas' story is that he recovered partly because he was diagnosed early, within a year if I got that right, and that he subsequently did everything right in terms of pacing. And had the means to rest properly during those first years.
Exactly what some ME clinicians recommend for having the best prognosis - early diagnosis and then adequate amount of time to rest and recover. Unfortunately many of us don't get that opportunity, mainly due to the health care and social security systems that are supposed to help us but instead often force us to exert ourselves beyond our limits.
My thoughts is that this guy was in a privileged position, or just lucky, not having to worry about finances or contend with Försäkringskassan (the Swedish agency for approving sickness/disability benefits).
I was doing really well and had improved a lot when Försäkringskassan decided to deny my application for sickness benefit despite what my doctor recommended. That stress and over exertion caused my health to plummet radically and I went from moderate to severely ill. What if I had been able to just keep taking care of myself? Would I have kept improving?
Jonas recovery story also made me think of a friend of mine: She became unreasonably fatigued and felt unwell after a travel to an African country where she got some infection, and having had the svine flu vaccine. This was a few years before I fell ill.
She went through lots of medical examinations for a period of two years or so. Looking at her heart, checking for sleep apnea etc. She met a neurologist.
During this time she was barely able to work, having a blue collar job with the government. She had a lot of sick days and flexible hours, came in late in the mornings, she slept in a designated room during extended lunch hours. At home she collapsed and just slept and rested. She also hade the means to eat out or order food so she could just rest during her spare time. I often visited her on the weekends during this time, bringing a movie and take away food. We just relaxed in her sofa and watched a film. She often fell asleep during the film or was to tired to talk
Anyway, after about two years she started to feel slightly better, enough to take some walks in nature on the weekends. Just before this time her GP had suggested she might have chronic fatigue syndrome (the words he used) since they found nothing else wrong, and that the next step might be a referral to an ME-clinic (I think it was at Danderyd at the time).
But as she started to feel better she didn't pursue any more medical investigations, she didn't feel the need I guess, and that GP left. Over the years she continued to improve and lives a pretty normal life today. But she often feels tired and after periods of much work and /or travels and social activities she feels like she's getting a cold, except she rarely does.
I've suggested to her that she might have hade ME and recovered to an almost pre-illness level.
I guess I kind of saw some parallels between my friends health journey and Jonas recovery

Not sure it's relevant , just wanted to share my thoughts.
