Have you worked very hard at learning to do something and could not perform when it came time to perform?

After preparing for weeks to perform at a dance in my studio, I was completely Shell Shocked at the 100+ people that attended. I failed miserably with my professional dance partner, and still cannot remember what I did, or how I did it. I have never been so humiliated with my lack of ability at that moment and trying to lick my wounds and press on. Has anyone had a similar incident and how did you handle or recover from it?

The AI response I got, even though I /we all question the source, made sense to me, and does help in licking my wounds

To make matters worse, my partner, my instructor, is a world class, champion dance instructor from Moscow, and beautiful, too. I wanted so much to be able to dance perfectly with her.
