Whatever the ideal would be, we don't have that. In the world we have, classifying it as "it is in your head" does marginalize the problem. But on top of that, you think it is a mental health issue based on your experience. There are millions of other people with ME/CFS (yes, I know there is currently no positive test for it, but is arrived at by eliminating other things) and the cause is (causes are) not known. By throwing it in the basket of mental illness, it means there should be no funding researching the physical causes of it. Finally, there are studies [1] which show mitochondria problems in many people with ME/CFS. That is, modest exercise causes increased cell acidity and/or slow reconversion of ADP back to ATP, starving the cell of energy. How can that be classified as a mental illness?
