One of my favorite references for things like this is from the original Karate Kid movie, right before the big tournament:
Daniel: Well, I'll probably get killed in the first match anyway.
Ali: So we'll leave early.
Love that she didn't say, "Don't be silly." or "You're gonna be awesome!" or try to convince him the thing he's dreading definitely won't happen. Just calmly points out that we'll just cope and move on.
And if there is some horrible thing that happens while you're playing, you can always loudly tell the audience...on second thought, never mind. The line is too dark-humored for a public forum 😉
Good luck today!
