I remember those days - I’m much older now - but I remember wanting to talk about it to someone and wanting a hug!! I just wanted acceptance and love!! Maybe try that. Having a stutter is SOOO frustrating - I wanted to cry a lot. If someone told me I have so many positive qualities instead of focusing on the stuff you wished you didn’t have - that would’ve helped me so much. So try that also. Big hugs to all especially your son.
