When I was your age I felt the same way. I was sick and tired of my stutter and I just wanted it to go away. I just kinda thought I would "outgrow it". But I never did. As I approached 30 and still stuttered noticeably, I realized if I was ever going to improve it was only going to happen if I worked on it. I read [Self Therapy for the Stutterer](https://www.stutteringhelp.org/content/self-therapy-stutterer-1) and actively worked on the techniques and exercises in the book for a few minutes every day for months. Doing this taught me a lot about how my stutter works and what I can do when I hit a block. I also learned that my stutter is directly related to my level of stress/anxiety. When I get stressed out, I stutter more. When I stutter more it makes me anxious and nervous which makes me stutter more, as I'm sure we've all experienced. This lead me to do things to actively lower my stress and anxiety, which not only help with my fluency but my overall mental health and appreciation of life. I started meditating and went at it pretty hard at first, with one 20-minute session a day for about a year. Then I backed down to 3 20-minute sessions, with additional ones 'as needed'. I also started taking a supplement called L-Theanine (found naturally in green tea) along with a nice dose of CBD daily. I'm still a little more tightly wound than I'd like to be, but I'm much more chill than I was a number of years ago and I attribute a lot of that to the meditation and the supplements. I'm almost 38 now and I still stutter sometimes, especially if I'm nervous or stressed, but for the most part I'm fluent in normal conversation. I even recently gave a presentation at work to an audience of over 50 people and only had like 3 or 4 blocks during the 30-minute talk. You can get there too, it just takes some work. Hang in there and keep your head up.
