It is difficult to find therapy groups anywhere, let alone groups that run with efficiency. We are only able to operate an active, structured program because I had social anxiety myself and I have had the experience of learning how to run groups during the last twenty-five years. Research was generally helpful to us, but it provided no specifics for what to do during the group. We had to come up with activities that would directly help people reduce their anxiety in real-life situations (and eventually allow social anxiety to be overcome). I made mistakes during this time, but we learned from our mistakes and each group became better and more powerful for the participants. I always hoped this process was going on in places throughout the world. Unfortunately, this doesn't appear to be the case.
The universities in San Diego have done a considerable amount of research on social anxiety topics, but your question related to receiving clinical help. To my knowledge, there is not an active, structured group in operation in San Diego county, but I could be wrong. Please check with the psychology departments at SDSU and UCSD ... in the past, sometimes they have run programs for social anxiety.
Around 2000, one of the best social anxiety therapy groups was being run in San Diego by a wonderful woman named Wendy Broadway. This group ran for several years and I was privileged to be asked to come over and speak to the group in September 2001. This was a wonderful experience for me because the San Diego program was large and several dozen people were learning how to overcome social anxiety. They were using our audio series (at the time it was on cassette and had just been released) so that no one had to become a cognitive specialist. I believe the group had tried to find a psychologist or therapist and failed in its attempt to find someone who understood social anxiety.
Anyway, please check around. Maybe there will be some way you can get here for the January or April session, or maybe I could be convinced to spend next summer in San Diego and run a therapy group during those three months. (I would need help if I was to consider doing something like this, but I would seriously consider it if enough people were interested )
