I'm sorry that happened to you; it's something I'm sure everyone on this subreddit can relate to so you aren't alone! People who don't have a stutter take speaking fluently for granted and will never know how much more difficult it is to present with a speech impediment. Try not to beat yourself up over it, the important part is that you got through it. Comparison is the thief of joy, so don't worry about how you did vs the others. I like to think of it as an iterative process, so each time you have to go through something like this it will get a little easier. This will seem very difficult, especially right now, but if you can get to a point where you aren't self-loathing or ashamed about it all... that's the key. Acknowledging your speech and limitations, being open about it with friends, classmates, advisors, helped me an incredible amount. Try to take the power it has back into your hands by just being okay with it and saying fuck it, this is a part of who I am, y'all can take it or leave it. I've found that making jokes helps alleviate some of my anxiety and stress that comes with it; started a presentation saying "if I get stuck and block on some words, it's just poor wifi connection and my brain is buffering", don't even have to say it can have it up on a slide. Just knowing the others understand that I have a stutter before I present helps me quite a bit; less pressure to be perfectly fluent, which ends up helping me be more fluent. Also when it comes to presentations, the better I understand the material the less anxious I'll be, which tends to lead to fewer blocks because I don't need to read from a script, I can wing-it more easily. I practiced my thesis defense I don't even know how many times... It feels awful now, but these experiences help build character and turn us into who we are. I've found that I'm a great listener, and a very understanding and easy-going person, which I can credit in part to my stutter. I did some assuming in this paragraph, so apologies if it's not all applicable, hope it helps!
