I think that is way too simplistic. Their could be many causes of CFS with one being undiagnosed depression. I my self was on the verge of being diagnosed with CFS after 1 year of being crook and would have been only I lucked out and got tested for a Ricketsia which came back positive. That test is reasonably rare to have done here so I think that's just an example of where people really do have problems but because the symptoms are so common they have not been tested for these rarer things or in the case of the really rare infections are just not known at all medically. On another note I can confirm having had it said to me several times by professionals that it is in your head, how devastating that is to the person being told and careful consideration should before going down that path.
