I’m 25 and I can say that I’m a middle-high stuttering because I’m always stuttering before beginning of EACH sentence as soon as I passed the 5-10 seconde of annoyance I’m good I can finish my sentence but it’s so annoying especially because I’m accountant and sometime I review client and stutters in front of them .I have started speech therapy and mindless mediation since 1 months and I can say that I can see some result . The key here is to practice public speaking and know how to breathe. I use a technique that I created throughout the year is before speaking I take a fucking deep full breathe with my months only I don’t involve my nose breathing . I meditate 3 times a day that allows me to not be ashamed of myself anymore and accepting my stuttering in front anyone I can say mediation helped me to calm down my anxiety. The app I use is called Stamurai everything is there like program you need to follow and Practice every day for About 30min during 6-9 months . I recommande this app because it helped me. I was lucky for social encounter because I kept the same friends that I was in university and high school so I really don’t need to socialize most of the time . For girl relationship I was also lucky because I’m 6,6 feet and not so bad looking (like 6,5–7/10 lol) I can say so even though it’s rare for me to do cold approach but I can easily go on dating app and I don’t have issue to have date and lay down girls . I’m still young so I need to work on my Speech so that I could cold approach girls but you really need to work men there is not shortcuts.. I hope I helped you.
