As a middle-aged bloke, I think I would have traded this disease for having no legs, but average energy. Sure I would have been cut off from various exercises and activities, but I also would have been able to pursue a career, start a family, have an easier time with relationships, and have my share of hobbies, presumably.
An example of one of the things that really crushed me was my pursuit of guitar. About 25yrs+ ago I bumblingly started with simple tutorials and internet tabs, and after a couple years found myself really humming along, my learning curve surprising me. Unfortunately, only a couple years later I found that I kept injuring myself via playing, sometimes via throwing my neck or back out, or more often my finger joints hurting more and more, making it harder and harder to fret properly.
Unlike sports, which I was able to play in small doses in my 20's, and which are a huge struggle for me today, I thought guitar would be something I could enjoy the rest of my life. Instead it became yet another pursuit in which I pushed through my CFS difficulties, only to be betrayed by my own body.
These doctors claiming psychosomatic causes are functionally nothing but quacks when it comes to true CFS/ME.
