Have I ever been just plain fed up with doctors??? An emphatic YES!!! I won't even bother to count the times. So far I've seen nearly thirty in the past four and a half years, and like you, I'm still chasing a diagnosis. I've waited as long as six months for a single appointment, and then got to spend ten minutes with the doc, who was supposed to be the best in our state.
There are others here who live with the double insult of suffering and not knowing why. I'm sure you'll meet them, and they'll really understand how much being undiagnosed adds to the trauma of an illness. We have no real "home" on these forums, so we tend to skip around looking for answers. In a way, that makes each forum a home...
I hope you find some answers soon, Quahog, and start feeling better, too.
