But in the end, you will have made at least some new friends and you will have probably gotten much more comfortable in social situations.
The catch to this is that you have to be consistent with your socializing. I had triumphed over my anxiety at one point in my life. However when I changed locations, I didn't really see the importance of socializing. As a result, my anxiety temporarily came back.
TL;DR make a socializing routine to overcome these problems and be consistent
