I might try a different doctor - it's pure hell isn't it - go in there armed with info and a good idea about one's health and they consider you a fruit-cake belittling their 'expertise'....go in there and 'play dumb' listing symptoms and they'll most certainly mis-diagnose you and give you meds you don't need!
Reminds me of a saying "Bankers destroying the financial system, doctor's destroying health, teachers destroying education, supermarkets destroying nutrition, court and law system destroying freedom....we live in a topsy-turvy world"
