Hi Sassy,
We have a wonderful organization here in the San Francisco Bay Area called, The Wellness Community. Everything they offer is free to cancer patients and their families. They have support groups, yoga classes, exercise classes, meditation, seminars on nutrition, etc.. The support group I participated in was one for those who were newly diagnosed with breast cancer. I don't know what I would have done without the group. We still get together (on our own) now.
Anyway, here is the information and I am sure if you were to call them they could give you some tips on starting a support group:
