Sorry to hear that, I also have a stutter since I was a little kid, now turning 27. What worked for me was fluency shaping and modification techniques and a LOT of practice. It's like practicing a sport, if you practice a lot you will gain a little bit more fluency at a time. Also, the cognitive part of it is very important, you have to feel confident and beautiful and competent (all the good stuff), and your fluency can increase right away. We only have one life, and don't beat yourself to much over it since it's the first time we are here, so enjoy the journey accept who you are and even if it is very hard, and I know, just do you. Don't care about what other people might think or say! We are the people we have around us, so suround yourself with people that make you stronger and help you in the journey, those you can hear closely! Awareness of your own stutter is also very important, try to anticipate the moments and decrease speech rhythm to check if it helps :) I research a lot about the latest reports and R&D around stuttering and I heard about a project called Fluently that would support this type of training with AI but its not release yet. Hope this can ,make tour day a little bit better :)
