What were your feelings when your product launch went live?

Hi there! It's Mary here. I've read a zillion instructions and tips on how to launch, but only a few have written about the purely emotional experience. Tell me how it went, how nervous were you, what were your feelings? I also want to hear funny stories :) Looking forward to your answers! I want to collect all your stories and sculpt them into a guide for people like me (a little unstable haha) And in general, how do you deal with burnout?
