90% of my speech is fine too. This one day we were at an event lunch. My boss introduced me to one of his friends from another company. Everything was going well until he asked me what highschool I went too. I couldn’t say my highschool name at all. I blocked so hard that my best escape was to act as if the food I was eating got stuck in my throat. That gave me enough time so sound it out… I look back and kinda chuckle but it is a horrible feeling. What has helped me a lot right now is not worry much about it anymore. It I block/stutter it’s ok. And sounding out my words helps too.
