Hi Mjgdub,
Welcome to the forum! Sorry you have had such confusion regarding your diagnosis.
Given the inaccuracy of the Lyme disease test, and the ability for the Lyme bacteria to "hide" in the body, the CDC has recommended that Lyme disease be diagnosed clinically.
I highly recommend you seek out the opinion of a Lyme Literate Doctor. Your experience with the antibiotic is more than enough to warrant that. That doctor will get tests done from their preferred lab as well as taking a detailed history.
If you need help finding a doctor, let us know.
