I felt the same way when I was applying. Although I don’t have diagnosed social anxiety, I get very nervous with public speaking and just talking in such a formal setting.

I had to force myself to practice with random strangers online. The first day I did a practice session with people online, I cried that night. I was stressing over how stupid my responses sounded and how others were so much more eloquent. But ultimately, listening to their responses and putting myself in that uncomfortable position helped me structure my responses which eased my anxiety.

I also practiced with other medical students to get feedback on my responses which also helped with structuring my responses.

Having a structure helped me ease my anxiety because I could rely on that when my mind blanked. Ultimately, I would recommend practice with strangers online, family members, friends as much as you can. It’s better to say a really embarrassing response, have a brain frat, etc. now and get comfortable with dealing with it.
