I wish I could give you an answer. I am in the same boat and have been for 9 months now but your situation won't improve at all unless you see a specialist. At least then, he/she can diagnose you and try different things to see how you react. I've had all sorts of tests done and so many are negative but with with each negative result, I can at least rule that issue out. Call now. Especially if your insurance if going to end. Also, I don't know where you are but you usually can extend your insurance for awhile if you pay it out of pocket yourself.
