Christmas party

The way i feel right now i never want to go to a party again!!!!!!!! Why can't i just go to a party and relax, and not worry later about everything. I also have social anxiety--it has gotten a lot better--but ooooh it is still there.  There was a time i wanted to be around no one, because if i did the anxiety whould come out in my neck getting bright RED!!!!!!!!! It would actually burn. Then when people noticed it they would say OH MY GOD LOOK AT YOUR NECK. Well that it all it took and i was a real mess!!!!!!!! I just wonder if this is part of OCD --what do you think????
