Hello. Just ran across this. I don’t have any advice since I have social anxiety as well. Just wanted to offer my support and send positive vibes and best wishes your way.

Things that help me are being mindful (staying present in the moment), saying silent mantras and affirmations to myself and asking lots of questions! I put the focus on the other person by asking them questions about them and their life. Everybody appreciates a good listener who shows an interest in their life and it takes some of the spotlight off you.

I hope all goes smoothly tomorrow.
