That's a partial bummer, but at least you can take another run at it in April, 2018. I would recommend having the mental health evaluation accompanied by a notarized affidavit from the doctor who signs off on it (if s/he is amenable to doing this) and also including a current copy of the doctor's CV. Not a guarantee to get you your concealed permit any easier, but it can't hurt to have the extra measure of preparation.
