In my case, the CFS like syndrome was all in my head in the worst fashion possible. After COVID, I developed a cross reactive species of antibody targeting my hippocampus and the opioid receptors in my brain. I have been bedridden since I was 17. I also manifested severe orthostatic intolerance and peripheral neuropathy that put me in the lowest 1 percent of neurite density. I was diagnosed at Mass General Hospital at a specialty clinic, so I trust the veracity of their claims.

The problem with CFS is simply that it is a syndrome. It is far too nebulous a label to be of much use. It describes everything because it describes nothing! I have an autoimmune disorder that debilitates me. I don't particularly care if it is labeled as CFS or small fiber neuropathy. @lindsaywaterman, I am curious about collecting a body of documents on my illness; I would be greatly appreciative if you could contribute your professional experiences dealing with CFS patients whether it began with an illness or was simply an unrelated psychological condition lumped in the same category on account of a superficial similarity in symptoms.
