Exactly! Thats why I mentioned, an expert in social anxiety can help you better compared to a speech therapist. A speech therapist with its speech techniques, increases your concentration on your words and stutter, which results in even more stress due to psyochological problems that has been stacked up since childhood. On the other hand a psychiatrist tells you to focus less on your words and stutter and concentrate more on the message you want to deliver to others instead. Have you noticed that you stutter less when you forget that you have stutter when talking to someone, like with a very close friend ? I strongly believe most of our stutter is pure psychological, at least mine was. The moment that you dont care if you stutter infront of others or not, is the moment your stutter starts getting better, and a psychiatrist helps you to achieve that.
