I think you are touching a very important subject here Azul! Personally I get the impression social anxiety can be treated and the persons dealing with this and only this can get a life totally without social anxiety with good and successful treatment.
This is what I sought after in my 20's. I did group therapy, psychiatrists, social experiments etc but didnt get anywhere. After a while I realized I had AvPD and now I am basically set with this life and know I wont get any better. But also its better because I now know I have to accept what I have and what I will never have. So no more treatment for me, I basically try to make the best out of it!

What about you,Azul, I am curious about your feelings about this
