Same here mate. I can sit in my room and read for 20mins non stop and not stutter once. Sometimes I think is it anxiety that causes us to stutter but then again there is times when I’m not anxious at all I’m front of people and I still stutter. It’s such a confusing condition🙄 someday I know there will be an answer and a solution it all, I just hope I’m still alive by then 😕 keep fighting 💪
