Wow! I hate that you had a bad experience with a doctor you are supposed to trust and count on. I would be so mad and I certainly wouldn't give him a second chance! But that is me. I would have never left the parking lot, I'd be back up in that office to confront him about discussing my situation without my permission (even if it was with dh). I would also be concerned about what kind of treatment he is giving me if he feels I am exaggerating or possibly has me confused with someone else. If I couldn't trust him to keep my personal information straight and private then I'm not sure that I could trust him taking care of me. I'm all for giving someone a second chance, but when it comes to something as important as my health and well being, well there are no second chances. Like I said that's just me though.
I sincerly hope that everything works out for you and all goes well with your TY treatment.
