Not going to argue but you just claimed that CFS/ME attacks mostly thoughtful, caring people by nature..
Or, having suffered enormously, we
become caring people from experience?
With regard to the rest of the thread:
The best miracle cure I ever heard of was laetrile for cancer. A clinic in Israel claimed everyone cured. This made headlines. A year later a reporter went back. Every patient was dead. Of cancer.
In the history of psychosomatic illness, claims to treat or cure occur regularly. They first claim an illness is psychosomatic, then claim they can treat or cure it. Like with tuberculosis, epilepsy, type 1 and type 2 diabetes, all cancers but especially breast cancer, lupus, MS, gastric ulcers ... its a very long list. There are ZERO scientific papers showing that any such claim has ever been extensively substantiated. As can be seen from my list, there are lots of cases where its been disproved.
Now I do not doubt that people can suffer from dwelling in unpleasant emotions, or have those resurface substantially outside of their control from PTSD. Nor do I doubt that various psychotherapies can improve quality of life. Nor do I doubt some patients recover. What is lacking is evidence recovery is reliably due to psychotherapy. This does not mean that the hormonal influences from anger etc. might not result in symptoms. They might. That these can cause specific identifiable complex syndromes is very unlikely though. Somatization disorders, and similar, are so far a myth, a religion, and one that is widely worshiped.
The idea that there are some psychosomatic/psychogenic illnesses, and that we can cure these, remains an open question. They have not been shown right once, and have been shown wrong many many times.
I have yet to see sound evidence that even one psychogenic illness exists. I think emotions can trigger brain injury, if intense enough, but its then a neurological condition. I also think that some learned thinking responses might assist coping.
Freud is discredited. He either knowingly engaged in fraud, or was incompetent. Remnants of Freudian theory, including conversion disorder, are highly dubious at best, and substantially unscientific. Even when more objective options are available its common for them to be rejected, like in the middle of the PACE trial with regard to actometers.
Its good when someone recovers. Its good that something can assist coping.
Its natural many of us will be sceptical of recovery stories for therapies that have been widely tried and found useless, and for which there is patently inadequate if not nonexistent science.
