I think with time and a lot of hard work it’s definitely possible, start reading books about stuttering, get a Speech Pathologist, and completely break down and reconstruct your speech. Some books I recommend are: Stuttering & Anxiety Self Cures by Lee Lovet Beyond Stuttering by Dave McGuire From Stuttering To Fluency by Gunars Neiders Mindfulness and Stuttering by Ellen Marie And maybe read some personal stores about stutterers like, Out With It by Katherine Preston I’ve read all the books I listed above, and I have to say that I’ve learned soo much more about stuttering, specifically more about the psychological aspects, along with very useful tools/crutches/techniques in order to become a better, more confident speaker.
