This sounds like a basic principle applicable to all states of health and every disease, and not a new or ME/CFS-specific idea--i.e. stress makes anything worse, while relaxation, a good social support system, and the like, make people relatively better (not cured, of course).
Just please, don't relate it to ME/CFS specifically because of the war between the good science and the malfeasant opinions. I know you don't intend to give comfort and support to the Hamans who are still in power, but it just comes across wrong. Thanks.
