I say get a new dr. but that may be hard in ur case. Research as much as you can and try to educate ur dr.. Maybe take printed literature to your dr?

Myalgic Encephalopathy shares so fibro symptoms

I had to see a LOT of doctors before any would even officially call it fibro. I honestly think my "official" diagnosis only ended up on my records between changing rheumies. None wanted to diagnosis it as fibro but they treated me for it nonetheless. Be your own best advocate. If your doctor doesn't take you seriously even seeing another at the same clinic (if that's an option) might get you a different perspective.

I agree with the previous answers. I was lucky my gp had fibro in mind while ruling all the life threatening stuff out and once we had done that sent me to a rheumatologist who took very little time in diagnosing me. You need medical staff who believe in this illness. Even though its proven its there some still hide away from it.
