Nor have I, in all my years as a medical student and my career as a doctor, ever encountered a case of CFS or ME that could be placed alongside any form of cancer. Such a comparison is grossly incorrect.
Your above statement suggests that you haven't yet witnessed how severe M.E. can be. Many are hidden away for years, bedridden in darkened rooms, unable to care for themselves. Some need 24-hour care because they cannot even turn themselves over in bed. According to Dr Betty Dowsett, 10% die as a result of this illness, and M.E. is now certified as a cause of death. The death rate is not as high as in many cancers, I'm sure, but if the majority do not die from it, they certainly lose their lives. This condition has been referred to as 'the living death'. I also refer you to my previous post to Linzi.
You say, quite rightly, that this illness does not cause people to become rude, abusive or impolite. Very sadly, however, many with this condition find that their doctors respond to them in just such a way. Fortunately, we have more than a few more enlightened members of the medical profession who dedicate a significant part of their careers to helping patients with this frequently devastating condition. It would be wonderful if you became one of them.
Your English is fine.
