Hi Donna, so good to see your positive attitude and receptive thinking.
The fatigue in 'CFS' was put in to avoid medical and insurance claims, and to give the illness a psychological twist, all of this putting it back on the patient as being self-inflicted. Very nasty.
That is why so many in the medical profession still treat it off-handedly and don't take it seriously.
People die from ME, and in Canada there are more deaths from it than from lung disease or AIDS, I just read.
Yet it gets no funding for research because of that medical confusion and mis-information.
If you'd like to find out more, have a look at my daughter's website, where she tries to unravel the name confusion; lists symptoms and treatments.

There is no treatment as such, but lots you can do and try.
If you come across 'CFS' again, you will now be able to straighten them out, and if a sufferer, guide them towards a proper diagnosis.
Sorry to keep on, but it is a VERY important thing to get clarified. You may save someones life.

I'm in Australia, by the way.
