Join the club. It seems like I'll be having an anxiety attack for days on end, its almost impossible to get work done and I'm extremely unproductive. Its happening right now. The teeth grinding is a problem for me too, as well as a plethora of other physical problems - I grind terribly in the night, and I have awful chronic pain... the doctors can't find a physical explanation, it seems my illness just manifests itself physically as well as mentally.
