I understand how you feel. I've been with my pdoc for 15 years after I'd been through many others. Each time I go in we talk for 45 minutes and he knows my condition well. If he retired I would be very upset because he is an important part of my support team. Have you asked your retiring doctor for referrals to someone like him? Change can be a good thing. Good luck and best wishes finding a pdoc that best fits you.
