I've heard of other people with a mild-moderate stutter that became severe as they got older. Met one too, a 28 year old dentist that had the worst stutter I've ever seen. Interestingly, he became the most fluent of all of the people that I was in group therapy with. Hope he's still that fluent! My stutter got worse than it was when I was a kid in my early and mid teenage years due to me constantly being stressed out, but things got better and so did my speech. Especially recently, now that I've started paying it more attention. Have you been going through a tough time, perhaps?
