?Influenza: Although this is an unusual time of year to to have influenza, or a flu-like viral infection, this is possible. What is of concern are the anxiety, delusions and insomnia. You are in an area of the U.S. In which lyme disease is prevalent. Strongly suggest you see your doctor and get diagnosed one way or another. Hope you are better soon.

Mind/Body Approach: I've had great success both personally and with clients using an approach that involves meditation and relaxation, along with traditional "qi gong" (a kind of chinese yoga) movements and postures. In addition, there may be something the symptoms are trying to tell you emotionally, regarding something that may be working from within. Psychotherapy can help.
