It is frightening to think of being judged in this way, especially when ill in hospital.The #1 feature of ME/CFS is the manipulative, obsessive need for sympathy/attention/drama.
While nothing we do will convince this person and others like him, I think this is another reason why we need to move to 'ME/CFS' as the name and leave ME well behind. Telling a doctor like this, or even someone half as bad that 'I've got ME', or 'My ME has become worse' or 'Could I lie down somewhere because I have ME?' is likely to have them sniggering about it all being about us, 'look at me, me, me'.
