You might be able to train yourself to view the event as an anthropological study.
IN doing that, I've become a bit better at relaxing and possibly breaking out of the downward social spiral in which having a socializing "handicap" feeds into anxiety, anxiety makes socializing more difficult because your nervousness exacerbates the already existent "handicap" and that in turn creates even more anxiety...
So for me now instead of trying too hard to actually make small talk, I try to just focus more an relaxation itself and not "forcing" small talk.
It doesn't totally fix everything, but at the very least you can possibly enjoy just listening to others talk, at least for a bit, and then you have more of a chance of contributing to the conversation.
All in all, socializing is its own type of transaction, like of mental "goods". People socialize to "gain" something.
YOu could think of the group as being mostly those sharing smaller, but numerous goods. But to you, it may be that it is best to share only a few "larger" goods.
I've just had to accept that I'm not good at small talk, but I can share things that are important to me much more easily. Your "social goods" may be less numerous, but have a higher value per unit (like in fiat currency) so the group can possibly have a lot of respect for you despite the fact you may not talk much.
Another analogy might be like, not being a performer per se, but how musicians might only sing a few words and /or play instruments, but a huge crowd will stand at attention for them. It's a huge transaction between only a few people and a few thousand, yet if all goes well, they feel like they've all gained something and feel happy about it
