Minimising everything so as not to be outing - a friend of mine has for many years had a panoply of ailments affecting every body system - skin, intestines, memory, joints, etc. I've always stuck up for her whenever anyone's suggested there's anything psychological about her condition, partly because I - used to - admire her very much as a charismatic musician, and partly because it seems so very rotten to disbelieve a friend who says she's ill.
However, of late a few things have made me disbelieve her - times when she's changed her story about a particular ailment, or when it's been investigated and nothing's been found.
There's nothing I can do, is there? She's obviously the person who's suffering the most. She really believes she's ill, and she's definitely not very happy. The rest of us have to do quite a lot of picking her up and cossetting her, as does her husband, but she's the one who's having the worst time of it. But I think if I were to say to her "look, So-and-So, do you think it might be all in the mind?" she'd be drastically offended, and it would have a pretty explosive effect upon my social grouping.
