I would also suggest some therapy. It is truly possible to reframe your thoughts and change your entire life. I’m a moderate stutterer, I stutter in most of my sentences, and I stutter fully and openly. I’m a lawyer. And I do that because I’m not ashamed. I’m not bothered. This is just how my brain works and how I speak. And I’ve gotten to this point through therapy and self work. You’re 25. You can change your major, get some therapy and transform the next 70 years of your life. Good luck.
