I think you should be referred to a neurologist if you haven't already. Many symptoms you've listed sound like migraine, and migraines can really make you feel out of sorts in a variety of ways. I think you should have an MRI done to rule out any physical reasons for these issues and I also feel that seeing a psychiatrist and therapist are in your best interest. If the doctors aren't listening, see another one. I know it's hard.....I've given up myself many times but you really need to get to the bottom of what is happening and you deserve to feel better.
