I other countries probably are, Mandy, and while I agree with you, I think people are more comfortable with a "diagnosis" because it brings them out of the unknown. It's a scary thing, not knowing what's wrong with you or having that definition shuffled around, because a definition can be dealt with, categorized, and fixed. An ambiguity, however? That's much harder to deal with.

Just my two cents, and again, thanks much!!
