I would feel bad about finding someone new so I would just tell him that you are gonna take a break from therapy for a while. I know others will disagree but I have a hard time hurting someones feelings. ESP when he has helped you and maybe he knows he has a problem and is scared to admit it. Being sick is hard enough but to loose your memory must be very hard. ESP when it is your job and livelyhood! He went to school for years for this and for him to just go get another job is hard. ESP one with the same pay etc.. Any way this is only my thoughts. Best of luck.
