this might help you mentally no one gives a shit , they see you you do your thing they forget about you and move onto the next one , in 2 3 4 days months or years no one remembers you . These people have their own fears, no one faces fear like you . every time you talk you face it you are a pro. You are going to get through this if you stutter or don't in the end you'll be done and that's that . Get to it, dont let it be an excuse i know you can do it, try not to think about it , i know this is easier said than done but you got this. ​ I have found all those moments that were hardest became the biggest pride because it takes me more to get through than most people but after years and years and years of this tense interaction I am strong and a pro and am not faded at all . they can sense that and inwardly they look up at me, were pros.
