Firstly, welcome to this forum! Secondly, I am so sorry you are feeling badly. In my opinion what you are experiencing is an overload of toxins that are released from the lyme bacteria die-offs.
Have you read the Detoxing Post in the Newbie Thread on top? I have been better for over 3 years now after being sick with lyme and ehrlichiosis for over 10 years. What got me better was not antibiotics but Dr. Jernigan's protocol which is all natural.
Most chemical antibiotics are actually made from plant materials so I decided to skip the chemicals and go right for the botanicals that Dr. Jernigan tested and then created.
Learn as much as you can, read as many books as possible. I suggest "Healing Lyme" by Stephen Buhner (amazon.com) and Dr. Jernigan's newest book "Beating Lyme" which can be bought at: www.hansacenter.com
Detoxing should be given at much attention as the medicines themselves (that includes the detox baths, dry skin brushing, foot baths, exercise, and lots more).
Hope this helps and that you feel better,
It's all about the Immune System mixed with a large dose of Positive Thinking and Daily Detoxing
This song is about my years with chronic lyme since 1995 and being in remission for over 3 years:
