Getting the bad news

So I FINALLY got to a recommended chronic fatigue specialising GP today. He started by asking what the "Dr" was for, and then when I said maths his whole face lit up and he started fanboying maths (apparently he seriously considered majoring) which was a nice start. He took my history and unlike all the vague handwaving I've gotten from other doctors was all "Ah, I know what's wrong with and how we can fix it" which was both encouraging and discouraging (I'm not sure anyone can be that sure with chronic fatigue)
( Nooooo! Don't take away my cakes! )
