Hi! It's great that you did it! I could never do it and chickened out many times during my college time. My advice to you is maybe to join a public speaking club like toastmasters if you feel like it. It is going to be harder on you, yes but you get so many tips on speaking, and you build confidence slowly as well :) Usually people from clubs like toastmasters are welcoming( idk where you are from). You can look it up and have a go :)
