well... i will have to think on this one....but it does sound to me like you don't need/want any of the things that a group can provide...so maybe you simply don't need a group.
I do wonder though...what do you get from SR....for me I get the same thing from SR that I get from AA/NA.....only thing is SR gives me a little more depth and f2f can give me some of the hugs and smiles and stuff that internet doesn't provide....course i don't have a close family group and am not exactly finding alot of friends just poping out of the woodwork...so if you have a number of close friends and relatives...maybe those physical presense things aren't missing from your life.
just intiial thoughts...will try to think it through more later
Glad you have been willing to really check out these differnt things and look hard at what works for you...that bodes well for your likelyhood of finding good solid and comfortable sobriety
