This, I think, is a very normal reaction. Somebody must have done something wrong. Perhaps it was the doctor. I'd guess they have their frustrated, angry days also. These feelings may be conveyed to the patient.
Personalities do count in dealing with healthcare.
A doctor that seems bossy to you may seem confident to someone else. And it makes a difference if you are used to speaking up or if you are the quiet type, or if you want to be part of the decision-making or just want to be given directions. While we often speak of doctors as if they were God or the devil himself, the truth is that they are just people. Some personalities we get along with better than others. One person I know of changed doctors over this.
