i personally didn’t see any positive results from speech therapy. i’m 24 now, i saw one for a little bit in high school but conveniently my stutter would practically disappear at my appointments because i wasn’t anxious about trying to hide it. that’s the whole reason i was there. she knew i had one so i wasn’t anxious and therefore wouldn’t stutter. kinda sucked bc i still had it everywhere else but at least it taught me my speech is anxiety related. that’s my 2 cents. :)
