I understand! I'm getting frustrated, following your nightmare journey. And yes, doctors are extremely arrogant. Add that on top of whatever constraints imposed on them (time management, restricted formulary from which prescription is permitted, etc) by the system, and I can imagine wanting to throttle someone!
But you said something that made me wonder... Often FNPs or even LPNs are more knowledgeable than MDs, and I wonder if for primary care management, that's a workable possibility for you? I'm sorry if it's another useless idea, I am unfamiliar with your healthcare system, other than what I've read online.
