I remember when I was in a group of people who stuttered, we were maybe ten years old, and one of us asked one of the counsellors if the stuttering would ever stop by age, she only gave us this saddened look and said it would probably have stopped by the age of 6. We all felt super doomed at that point. My stuttering however, has become much better. The therapists really helped. I really felt doomed at that point, like there were no getting better. It's not gone now, but it is better. Would definitely recommend therapy!
