I have very mixed feelings about this. On the one hand, It's really easy to see how this will be used by some doctors to say "shut up and stop whining! Oh, and I'm not going to treat your actual physical symptoms either."

On the other, I've seen people who get caught up in their ailments and make a vocation of managing and worrying about them in ways that make it hard for them to do other things and hard to be around them. And if that can be recognized and treated (to some extent separately from the ailments themselves) there will be benefits, like those people having more time to actually live their lives.

(And I think, with others, than there is a difference here between obsessing about symptoms of illness and obsessing about other stuff -- in particular the fact that the illness is actually there.)
