And my (personal) experience with GPs says that, well, I can't trust them with anything chronic (4 full years of completely mismanaged care, in my case, did this - though I believe that doctor and their staff were just epicly incompetent). After another doctor told me to "find Jesus and get thin again," (not to mention saying that my depression and thyroid issues would be miraculously cured if I became a born-again Christian instead of using proper medication and therapy) I decided that, well, for my thyroid issues only a specialist will do. Then again, I think the doctors in my area are specialized in idiocy. Thankfully I have fabulous insurance.
