Awesome. Broke down three possible causes of what was ailing me. Gave me a course of action for each and did it so a 8 year old could understand. All without condensation

Appointment lasted approximately 10 minutes and didn't hear any my concerns. Called my diagnosis just "labels" and then went on to talk more about therapy for 5 minutes straight. I've been living with my conditions my whole life and never once said I was actively depressed or anything like that. The cherry on top was that when he said goodbye, he just left me there. Didnt move the table out of the way for me and my mobility device, and didnt even show me the way out. If my condition(s) get worse, I would NOT trust him with my care.
