I turned to improv for exactly this sort of thing. Signed up for improv classes and did that 2-3 nights a week for a couple of years. It’s a lot more than just “yes and”.
That helped to re-train my brain to see everything as an offer. I developed the skill to just be in the moment and own whatever I say or do. I learned to just let that awkwardness go when the “scene” is finished.
I still have social anxiety and I still ruminate some on awkward encounters, but I’m way better now than I used to be.
Highly recommend an improv class if there’s anything like that in your area.
I’ve seen it called smallweb.
