There is a very good Lyme support site which can refer you to an LLMD near where you live. From there your treatment should improve. If you've had a positive Lyme test from a regular lab, it is really imperative that you get into the hands of a good lyme doc, as there are so many co-infections that the same tick carries that must be looked for.
I think if you find a good lyme doc, you will be on a better road. There is a road to healing with Lyme.

If you ask about how to find a doctor you will be directed to the correct links. ILADS i think also links to doctors who belong.
Good luck, it's less scarey to have a known than an unknown.
