Hello! I’ve just completed my presentation too. It was an individual presentation. I started off very nervy and had several blocks. What I did was to substitute words that I could use to prevent from blocking. And I kinda pulled it off. Try doing what I did and maybe it’ll work out for you. Stay strong friend, you’re not alone 😊👍🏼 Update: Friends shouldn’t tell you off for stuttering. My classmates understood my condition without them asking about my condition. I’m sorry but they’re just not your friends.
