Look here for a listing of support groups:

I'm sorry I don't know of any support groups in the physical sense...I used MedHelp as my support group for all 72 weeks of treatment. It was hard enough just to get out to work all day and sometimes it was hard just getting on during the weekends to type!
Be In Charge might know or a local hospital?
