I completely relate to your concerns.
I had a very bad experience at a doctor's office so I was really reluctant to go to a doctor. When I weighed in, the scale was in an open area near the receptionist's desk and the nurse said my weight out loud - in front of other people! The doctor told me to exercise seven days a week and to "watch every bite I take". He actually yelled at me and then rushed out the door to the next patient. I was so upset that I thought I would never find a good doctor that is right for me - and it took me a long time to even try to go to a doctor.
What I did was to talk to different people and ask them about their doctors and their staffs. Get a referral from a friend, neighbor or family member. Ask about their style of dealing with patients. My boss referred me to a terrific doctor and now I go regularly. I hope you can find a doctor with a staff that are supportive and professional.
Best wishes to you. Please keep posting and let us know how you are doing.
