I also suffered from a bad case of social anxiety. It probably does not work for everyone, but what really helped me was just going away for 4 weeks. I just returned from my holiday and forced myself to stay in hostels. I was terrified before (having to socialize with unknown people, blegh), but it has been amazing and am really looking forward to doing something like this again.
Again, I know it does not work for everyone, but sometimes throwing yourself in the deep, away from your own comfortable home situation, works wonders.
