I am so sorry for all of your ailments. They aren’t your fault and any doctors who tell you they are, are bad doctors. Your brother is a simple bonehead and his opinions should not matter, he is totally stupid. Best of luck. I know changing doctors is very stressful. I was forced for insurance reasons to leave a medical group I have been with for 10 years and boy am I hesitant to select a doctor without first interviewing them or a meet and greet. Unfortunately, that’s not the how the system works. May the lord bless you and give you strength, grace and love!
