I have been attending a social anxiety support group for the last month and so far I feel it has been beneficial to me. However, I realize the support group is not treatment it is a form of social support. I had a doctor's appoinment last week and he faxed a referral to a social anxiety clinic. I just want my life to change now. I feel really motivated for change and I want it. The issue now is dealing with the frustration and the feelings of not being productive and loneliness.
It sounds to me that you are in a point in your life that you have the time to focus a lot of effort on getting better. It also sounds like you are completely committed by being ready, willing and able to do what it takes. My recommendation is to see a cognitive-behavioral therapist who specializes in anxiety issues and has an expertise in treating SAD. CBT has by far the most backing from the scientific community as an effective therapy for treating SAD. In addition, therapy is quick (generally 10-20 sessions). There will be exposure involved which requires you to get out there and face situations that you find fearful but will give you the tools to be able to cope with the fear.
