You are me. I have had the same symptoms, extensive labs done, many trips to the doctor, finally ended up at a psych for extreme anxiety/depression. finally was tested for Epstein Barr Virus. There is a site for that if you are interested: chronic Epstein Barr Foundation forum. It is the virus that causes mono which I never had. 95% of us have it in our bodies but stress can allow activate it. even though there is no real cure, it was almost a relief to me to find the cause of my problems–now the fatigue is my worst symptom along with extremity weakness. I really thought I was a total hypochondriac and had the feeling my doctor was humoring me for awhile. Good luck. I hope you find an answer–it will certainly rule your life until you do.
