Grad school wasn't too bad for me, my candida affects mostly my appearance, and grad school is one place where most people won't pick on you for being "ugly." My brain always functioned okay, and although I was depressed and had a flat affect I always enjoyed studying and learning (I also liked the idea of setting my own hours instead of having to go out and work full-time.) What were your symptoms from candida? It would be nice to communicate with someone whose been through the same thing...the candida diet is very challenging! I haven't had a piece of real bread for years.
Again good luck
