Year_24 gives good advice. Pretending you don’t stutter is one way of doing it, but he’s spot on when saying your attitude in stuttering changes. That’s what helped tremendously with my stutter. I, much like you, would self isolate a lot and it affected a lot of my social skills to this day. I also got a lot a lot of grace in school like not having to present assignments in the front of class, but long term none of that helped. If anything it made things worse because I was avoiding any work I could’ve been doing towards my stutter. After high school I picked up jobs at Starbucks or restaurants and at first I was terrified of my own stutter, but after dealing with customers I noticed my attitude towards them was stronger than the attitude towards my stutter. I wouldn’t think too many things like "oh no Im gonna stutter" but instead "i need to get this guy the fuck out of here so i can close the store" and bit by bit, i was stuttering less. So much less that new people I met didn’t notice my stutter. It was the same thing with girls. Talk to one, stutter a bit but start to get comfortable, talk to five and forget you have one, talk to ten and then no girl notices, and when they do they think it’s cute. The only place my stutter really acts up is my flight school because I’ve had some trouble progressing and I get self conscious of others opinion of me, and then that attitude turns itself back in on my stutter. I’d take some time to watch the movie The Kings Speech, and look at Samuel L Jackson’s career. He had a speech impediment his whole life but he’d more upset with the script than his own stutter and then get through. If anything, it’s good to think of your stutter as a symptom of a lack of self confidence. The worse your confidence is, the worse your stutter.
