Ah, this reminds me of a time when I had to recite a lengthy french poem for class. I spent a lot of time rehearsing until I knew all of the words by heart. Then, on presentation day when I had to recite it out loud in front of the class, i completely froze. Mind went blank and started sputtering and stuttering for an uncomfortable 5 minutes. I thought i would never be able to face my class again. I felt like my world was over. That was 22 years ago. Yes, it was traumatic and I still remember that distinct burn of embarrassment. But I'm still here. I'm working in tech and even though i stutter much, much less, it's still there but eh, what are you gonna do right? Gotta keep living. There will be bad teachers who will throw you in the fire. Then, there are ones that coddle you and protect you. At the time, I wish I had the latter. But it's the trial by fire that makes ya grow and level up. It sucks that it has to be traumatic but honestly, it made me stronger and more prepared for real-world situations that count. Be mad at the teacher, but don't stay mad. Just regroup. Practice, practice, practice. Stuttering has given me such fucking tough skin that nobody else has because nobody else has this stutter as it's very rare. Sure, it's a curse but it'll make you tough and it'll make you strong. It's not going away anytime soon so own it, suffer with it and but mostly, learn from it and accept it and make peace with it. Good luck!
