That's terrible, sorry you have to deal with those things but I get it, back in high school my stuttering was terrible. It got better over time though I'm in my late 20's so it's mellowed out a bit. Give it time and I'm sure you'll be able to control it a little bit more. My story comes from my old job, I worked as a host for a hibachi restaurant, I loved the job itself however on nights when we would get super packed it made me slightly anxious just needing to deal with that many people because of my stutter, not everyone is understanding about it. But anxiety makes me stutter more regardless even if its only a little bit of anxiety. While dealing with these guests I stared to stutter more frequently then I regularly do and trip on a few of my words and this guy assumes I'm impaired. He started asking me if I was high or drunk and after I denied he didn't believe me and got my boss causing a big scene and making people believe I was drunk or something when I was not. My boss was good to me about it, she knew it was just them being an asshole but I still couldn't go back out there while everyone else was. I was no longer am allowed to work with the customer's though and had to stay in the back because they didnt want there to be any more encounters
