Hey I’m sorry you had to go through that. I went through my fair share of embarrassing class presentations. Like one time we had a group presentation and when it was my turn to speak I couldn’t control my stutter and that took my group members by surprise because I didn’t stutter that much through out our group discussions and meetings pre-presentation. Ive learned now to seek help if I know my stutter will hinder my presentation performance because sometimes I can control it but sometimes I can’t. By making my professor aware of my stutter I have certain accommodations that other students don’t have or if it’s a group project I focus on the research and let others present or if I’m comfortable around my group members I let them know of my speech limitations so I don’t get a long speaking role in presentations so I contribute more on the research portion of the assignment. I hope this helps you in future cases. We can’t help what we have but we can create an environment that can help us. That’s a tough lesson I have had to learn this way too 💔
