I have/had social anxiety (it was much worse in school). Now I pretend that I don't have it, and it works somehow, 'fake it till you make it'. Instead of sitting at home (I'm an introvert) I started going out alone. Now, it's much easier for me to go out by myself or talk to people. I still need to work on my communication skills more. But so far I've seen progress in myself compared to few months ago.
