Hi, I also stutter. And I have very big problems telling something in front of the class, even the most ordinary verse is a problem for me. But I deal with it like this: 1) I make a copy of the presentation on a piece of paper, and try to memorize it 2) I try to speak only on the exhale 3) If I find it difficult to say a word, I try to replace it with another one (All these tips helped me before, but now I can't say hello normally for me this is a big problem. I hope my advice will help you and most importantly do not worry)
