I know how you feel. I once spoke in front of a large group of my piers and totally blew it. It felt embarrassing. I’ve since taken public speaking courses and I’m comfortable on the stage. You were nervous in that moment but you had the courage to ask anyway. You should be proud of yourself and congratulate yourself for having the courage to ask an honest question when nobody else would, and most of all, forgive & love yourself. Many people find it difficult to speak in public or at times loose their train of thought and get nervous. Its fine. You are human. Public speaking is the worst fear for most people. If it really bothers you, decide to learn to speak in public joining a public speaking club or take a class. It’s the best feeling to take a “negative” experience like this and build it into a strength.
