Hi fivejelly, welcome to the board!
I am sorry things have been so difficult for you. I am glad your friend finally got diagnosed. It is my understanding there are rmore likely false negatives than false positives. Which test did you have done and which lab did the test? You have a positive test and symptoms, you should be treated.
Below is a Lyme disease symptom list. You can have any combination of symptoms.
Unexplained fevers, sweats, chills, or flushing

It is very important to see a knowledgeable doctor. Many doctors do not understand Lyme and treat with outdated protocols. No test is completely reliable, and results can vary by lab. Besides Lyme, ticks can also transmit several co-infections including Babesiosis, two types of Ehrlichiosis (HME & HGE), Bartonella, and Mycoplasma. Many people who have Lyme are co-infected. It may affect treatment choice and progress. It is important to be tested for these by a Lyme reputable lab such as IgeneX in Palo Alto, CA. Have you been tested for these?
If you need a doctor recommendation, you can email me at email@example.com
It is also important to learn as much as possible. I recommend reading Dr. Joseph Burrascano's 2005 Diagnostic Hints and Treatment Guidelines For Lyme and Other Tick Borne Illnesses at http://www.ilads.org/burrascano_0905.html He is one of the top Lyme doctors in the country, and many Lyme doctors follow his protocols. I also recommend the books "Everything You Need To Know about Lyme Disease Second Edition" by Karen Vanderhoof-Forschner and "The Lyme Disease Solution" by Kenneth B. Singleton MD.
I hope you can get treated soon.
