Man you have some work to do... No usually it does not get better by itself but it can definitly get better if you take action.
So instead of making gross generalizations and discouraging statements you could start by letting us know what was your course of action to reduce your sa so we can try to help.
Allez courage !
Discouraging perhaps, but I'm simply offering a different perspective.
I don't have a course of action.
My social anxiety, severe as it is in social settings, doesn't generally manifest itself in education or work matters. As such I don't think it has impeded my professional progress. I guess I always assumed that as long as I was financially and professionally secure, I could handle the social isolation and find solace in solitary hobbies.
