Two quick points of clarification: For a while fibro and empty nose syndrome were considered psychosomatic until physical causes were discovered. I totally agree with you that psychosomatic conditions are not “made up” or “all in your head,” I was trying to convey that the diagnostic criteria revolves around observable traits and behaviors rather than something concrete like a blood test.

My larger point, though, is that CFS is likely not a single disorder and instead is an umbrella diagnosis for several distinct conditions that aren’t well understood (yet).

I don’t actually think we’re in disagreement I think I just worded my post poorly
