I’m sorry to hear what your son and you are going through. I think one thing that he should consider is whether the stuttering is actually the main reason why he doesn’t have friends. It may be more due to him having low self-esteem in himself about the stuttering. Or it could be due to any other reason that he can work on. So I think pinning it all on his stutter can limit his potential in having a good social life. So he should be a little bit more open-minded. However I understand that kids in high school can be brutal. So I would really recommend the Dave McGuire course. They have an inexpensive self help book on Amazon called “Beyond Stammering: The Mcguire Program for getting good at the Sport of Speaking.” You can have the book downloaded onto your phone in minutes if you get the Amazon Kindle app. The book will go through psychological reasons for stuttering, give you a breathing technique, and inspire you to get out and practice speaking. The program will be fear inducing but use the people closest to you for support. Keep practicing the techniques and follow what the book says. Then I recommend reading “Redefining Stuttering” by John Harrison, someone who stuttered for many years and was part of the National Stuttering Association for many years. You can find a free link to the book if you google the title. If you can’t find it I will help send you a link. I was surprised to find the book for free after seeing it was sold out on Amazon. Also, the YouTube channel “Stutteringmind” is very helpful! Rama stutters but has confidence higher than anyone I know! The channel “Stuttering with Olga” is also very helpful! The channel cgstutter is so helpful too! He’s a young man that stutters, but has a lot of confidence! He’s happy with himself, and says women even find is stuttering sexy. They all do coaching calls as well! Let your son know that he will gain resilience from these times. And that school is just one phase in life. But I think it’s possible for him to make a lot of friends. Especially if he gets a therapist that can help get his social skills higher than the average person. And correct inns yes beliefs. Maybe Cognitive Behavioral Therapy. And maybe a few mentors to push him out of his comfort zone. And someone to help him dress very well. Because sometimes it takes overcompensating in some areas to build confidence. Also, as a Christian, I would really recommend you try out God if you aren’t already. Have a strong Christian pray over your son, and begin to follow God. I feel God has opened many doors for me to work on my own self to better my stuttering. I have a friend that grew up stuttering in school, and was bullied for it. Now he’s one of the most confident, relaxed people I know. It used to bother him so much, now he stutters still a bit frequently and he barely cares. And on top of that, he owns his own roofing business and makes around $20,000 USD per month!
