Welcome to the forum! If you haven't look already, check out the thread titled, New To Lyme?.....Start Here!" There is some great information in there to help start you on your journey with Lyme.
I agree that there is probably a co-infection involved. You definitely need to see a Lyme Literate Medical Doctor so that you can be checked for this and receive the correct treatment. The fevers may be Babesia since they get elevated like that.
I always like to post this website page because it is full of information including what antibiotics to take and how much should be given.
