I thank for your full-of-knowledge posts. The anxiety part shouldn’t be overlooked. If a person has leg weakness for instance. He knows he can’t run. That’s a fact. It does not change. And it does not cause anxiety in the long term. Because you know your limits and accept it. But if you have a stutter it changes. Someday you speak fluently Some say you can’t. Someday one letter someday the other. I think the anxiety part comes form this unexpected things. The loss of control feeling makes anxiety.
