I feel ya. When I did speech therapy an activity we did was call stores and ask them what they had (in my case I’m an athlete so I called a Nike store about shoes). The first line was “Hi my name is nhaire123 and I stutter...” fucking terrifying. Turns out that people don’t really care if u stutter or not. The next step was to do that in person and do a questionnaire about stuttering. Again turns out people won’t laugh u out when u tell them u stutter. Hang in there!
