Kathleen,
If you have Chronic Fatigue Syndrome then there is hope. I'm not sure if there is a cure but there was (retired now) a footballer here who was diagnosed with it. He trained and played pretty vigorously so I think he was "managed". I do know that he didn't train 5 days a week like the other players and he didn't always fly coz that seemed to drain him but he did manage it pretty well. It knocked him around for around a year until they (the teams medico's) actually worked out what to do.
Maybe, you need to research it a little so you can manage the problem. By managing, I guess that means doing the right things and not the wrong ones. Got nothing to lose as I see it but if this guy who played till 36 could play professional footbal with it, then there is hope. The footbal is Aussie Rules and in case you are unfamiliar with it, its very different to gridiron. This guy would have run around 6-8 kilometres a game and be bumped and tackled a number of times. You got to be really fit to play this game.
cheers
Larry
