Unfortunately, you are at a point where so many of us were, or still are.
Keep your chin up, keep a journal of your symptoms, and don't give up...my DD worked with a woman this summer who finally got dxd 20 years after her first sxs...too late to help the neuro problems she was stuck with...she was told that she was crazy, that she was imagining the sxs, that she was depressed...still, she kept on searching for a doctor that would work with her, and they finally dxd her with MS.
I had been searching for an answer for the strange sxs for almost 4 yrs. Finally got a dx last month, am now on meds...now I'm not sure if I want the dx...but it is what it is.
Again, don't give up...read the various sites to be a well-informed health consumer...and try to live a healthy lifestyle.
Good luck...
