I started stuttering at 17, I’m 29 now, life is better, way better, and my stutter is not a major issue in my life anymore, I still have it but I have a lot more control over it. I just say this so you don’t give up, or put yourself down. Keep your head up, look up a good speech pathologist focused on stuttering in the adulthood. I suggest you reading the books by Dr. David Shapiro, he is very close friend of mine, and he’s the one who changed my life. Feel free to DM me, and I can talk to him to see if he’s still willing to take new patients.
