free? as in cured? no I don't think that's possible. its not that black and white. I think being anxious in social situations is normal from time to time. I think even the most confident and outgoing people have experienced some discomfort and anxiety in a social situations from time to time.
its more like a spectrum of severity. it really is only an issue when it has an adverse negative effect on the quality of life you want for yourself.
sorry rambling... in short, I believe you cannot be completely free from SA. however, I also believe it CAN be overcomed to the point you can live a happy healthy life, providing one has the will power and support to better themselves for themselves.
so I'll answer as a yes in this context.
