Hi Cindy!
Welcome to our community! I'm so glad you found us.
If you haven't yet, it would be helpful for you to start with reading through the thread at the top of the forum titled,"New to Lyme?...Start here!!", as it is packed full of important information, symptom lists, helpful links and pdf's, how to detox when one has these infections, information on probiotics and much more.
And, here's another good place to find helpful detoxing routines:

You said that you have every symptom of Lyme, and were diagnosed with Fibro for a long time - that sounds like quite a few members here, including me - yet we really had these infections all along. As PeteZa has said, your doctor is trying to get your body prepared for treatments. Detoxing and eliminating sugar are two big steps in that direction.
Keep asking questions! The learning curve for these infections is incredibly steep! We are here to help you as much as we can.
