Social anxiety is quite a common issue to struggle with. I deal with it daily, alongside my other issues. In my case I can't stand social gatherings, I hate to be the focus of attention for any reason, good or bad, and I even struggle going in to pick up a takeout or pay for shopping. It's a struggle I've lived with forever, my therapist believes the best means of combating this is via distraction techniques. Things like the five senses game (what is something you can see right now? what is something you can hear right now? what is something you can smell right now? what is something you can touch right now? what is something you can taste right now?). These work to take your mind off of your situation and focus on other things, helping reduce the anxiety and allow you to get through the ordeal It's not something that works for me in every situation, but I admit it does indeed help at times!
I would consult a therapist if you ever get the chance, they're invaluable in dealing with your struggles!
