i feel bad for you being surrounded by horrible doctors. They clearly dont care about you and misdiagnosed you. So much exploitation. Anxiety can worsen stutter but its not like you'll stop stuttering if you remove anxiety. For the words to come out we need more brain power than non-stutterers, its why some of us dont stutter when we are in a high intensity situation, because we use more brain power. Your medicine sounds like it reduces your brain power doing the exact opposite.
