I'm also having a rotten, crap time with the doctors. They are dragging their feet in diagnosing me (hurray for the Canadian medical system).... and meanwhile I continue to deteriorate. I recently had to start using a cane, whereas 3 weeks ago I was able to use my legs effectively, and only suffered from upper body symptoms. Like you, If I hear another 'anxiety' related diagnosis, I'm going to snap.
3 useful things to say to doctors if anxiety is brought up.
1) When Polio first appeared doctors considered it a psychosomatic condition.
2) Ask them *sarcastically* if they have penis envy. Freud's nanny apparently had MS and he diagnosed her as suffering from a type of 'female hysteria' (meanwhile she continued to become increasingly more paralyzed)
3) You can also bring in legitimate internet medical studies in i.e. PubMed stuff to substantiate any claims you may have. Make them read it! Many doctors are astoundingly ignorant. Especially GP's. They have no grasp of current clinical research.... they are at least 5-10 years behind the rest of the world. Your health should not be left in their, elitist hands alone!
You can always try homeopathic remedies too, if nothing else. Most are probably not as effective as allopathic drugs, but likely better than nothing. In my case I don't know if I should be supporting my immune system (for possible Lyme/cfs) or diminishing it (MS/etc). ??????????
Anyway, I've been taking green tea, Omega 3 fish oils, Sub-lingual vitamin B12, and curcumin lately. There are many studies that substantiate the effectiveness of these treatments in neurological conditions. Granted, the results are probably going to be pretty subtle when compared to prednisone or whatnot. Or interferon.
So yes, very frustrated. Still waiting for my *&@#@)$* MRI results!
