I know how you feel. the first time I ever met any other head and neck cancer patient was three years after my diagnosis, and that was at a SPOHNC meeting, and just had one on Thursday, Have you tried them? They have chapters throughout the country, and meet once a month. There are others, non head and head cancer, like Gilder's Club, which I never attended, but heard they are good. Check your local hospitals, treating hospital, to see if they have any. Maybe you can start your own support group with the help of your hospital or other organization. OCF have walks that maybe you can participate and or help organize or start a new one. See ChristineB for that.
