It shattered me today

It shattered me today I was giving a group presentation in class. Initially we played our presentation slides which had my video throughout and boy what a stutter it was throughout. The whole class which wasn't paying attention suddenly had their heads up to see my speech. If that was not done, I had to further explain a document in the classroom. As I was going to the stage I heard noises like "not him again" and "can anyone else make it quicker we don't have the whole day". I barely was able to speak for a minute, just wanted to end my line and hand over to my partner. I have been a stutter my whole life. Wanted the earth to swallow me that moment.
