I'm so sorry. Do you think it has anything to do with your breathing? Did any circumstances change in your life that might have caused trauma? I overcame my lifelong stuttering at 70. I really believe breath has alot to do with it. There's a protocol, the Mcguire technique demonstrated in a video I'll post. If you think you're stuttering has any tie to your way of breathing when you speak, learn more about the various successes on YouTube ‘stuttering’, and the Other techniques that have helped others. The video link to ‘Stammer School’ follows. https://youtu.be/bNkOeIBKZNs If you lose the link go to: YouTube ‘Real Stories Stammer School’ these stutterers couldn't even speak their names and within 4 days were communicating with strangers! Keep me posted if that video was interesting to you. Good luck, Sue
