Hey bro, I related to a lot of what you just said. Although I feel like advertising it to people I come across that I stutter takes some anxiety away, Im always worried that I might change the way they look at me. E.g. looking down on me. Speaking slower does help to a level but theres is always that moment that your too anxious and just cant get the word out. I've been through 4 years of uni, and the only issues I had so far was the phase where we had to introduce ourselves to the class, oh the horror. But other than that, I managed to avoid most verbal contacts as possible so i wont have to embarrass myself. But I understand thats a shitty way to live, but what more can i do. Anyway, thats my 2 cents, take care buddy.
