It took me a while, GC, before I attended dinner functions without feeling a little 'out of sync' with the other diners. I was a little 'hyper-sensitive' to the sight and sound of the wine being poured into the stems, etc.
That's no longer the case; the wine and cocktails are pretty much the same as the flowers or candles on the table.
I am confident that you will reach that point, too.
Have a nice time with your friends.
