Second Opinions: Fibromyalgia or Multiple Sclerosis

It's been over 5 years since I was diagnosed with Fibromyalgia. I have tried several different medications and treatments, as well as homeopathic remedies to get it under control, but aside from mildly easing some of my symptoms, none have worked. I have not only not improved, but I actually seem to be getting worse and have acquired more symptoms that aren't usually associated with Fibromyalgia. I have spoken to several doctors in 3 different states. I have had so many problems with doctors here in WI contradicting results from ones in NJ/NY, not listening to my issues/ concerns, and even out right dismissing me outright. I have had so many tests done by all different doctors and after a new test all of a sudden, things shown in results from previously done tests are all normal now, though it's not actually possible to miraculously have them disappear. I have had some doctors tell me that the symptoms are not consistent with something suggested by another doctor even though they are. I have been on more medications and through more treatments than should be possible only to have one or 2 symptoms eased and to now need another medication to deal with the side effects from the first medication. I've also been fighting with Disability for almost 5 years now and since they continue to deny me, I have no way to support myself. I am on Medicaid and receive food stamps, lost my car (which I wasn't able to drive much due to my health), I've been evicted, and almost lost my cats, and have had my power shut off. I'm not supposed to be using public transportation and as well as help getting around my apartment and even have trouble staying awake. I need some major advice, but I know it will take time to explain my conditions to someone and have idea what to do. Can Someone help me out? I don't know what else I can do..., who else to talk to. I'm just lost. Please.
