The psychosomatic view of ME/CFS was and in many places remains the expert opinion and one that I agree is misleading and damaging. It was pushed by a highly influential team of British psychiatrists. Many countries still prescribe exercise as the official treatment which is horrific, especially when MAID is given as an alternative. I’m understand of skepticism.
My position is that of a subset of the patient community that represent motivated amateurs rather than any sort of official expertise. My background in ML and stats did help in my research and my ability to solely focus on this one condition and rapidly iterate small N unofficial trials over many years led to findings that I contend exceed that of most experts. For example we knew the BC007 trials were going to fail years in advance of when they actually did.
