Oh yes, I totally understand (and do not begrudge) envy of having a diagnosis, I've been in that boat myself. I mean, part of me is almost glad I got so bad the doctor had to give in and admit I had chronic fatigue, since it's been eight years of "Maybe you just need to eat more vegetables", "You've just had a series of identical virii", "Have you considered antidepressants?" etc. Bah.
