I understand how u feel bc I've went through many embarrassing moments too. But it's totally alright bc it's just temporary, as time passes by, people who witnessed those incidents will forget everything. Ik it's hard to stop overthinking on how people might think of you but tbh they're even busy with their own problems and they might also hv their own embarrassing moments. So they won't spend their time judging you bc gradually they'll forget about it.
