Feelings are feelings, nothing dumb about them. I’m 9 years older than you, so I still see myself young but I have embraced myself as the stutterer of the group since maybe 17 or 18 and that’s not a bad thing at all, depends on your perspective. Like ya I have stutter and am open about it with everyone including mu friends. Best decision I made and actually improved my stutter. I know it’s very counter intuitive but if it works, I’ll take it. Even my current speech therapist recommended that I start my presentations with something along the lines of “I’ll be slower than usual now, so I can control my stutter” which at first sounded terrifying to do but after a while of doing it so casually it paid off greatly. Also, as you noted, you have to remove the negative thoughts from your head completely and always stay positive. Remove the idea of “ya I spoke well now but I’ll stutter the next time”. We all now that we’ll stutter sooner or later and we’ll have bad days and good days but thinking that way actually makes it worse. I know it’s easier said than done and I had to work real hard on myself to get to the point of thinking positive about everything in my life, not just my stutter. My advice would be to meditate and think of a mantra that will keep your spirits up and move you forward each time you say it to your self. That’s one trick I learned and had helped me a lot.
