You are definitely not wrong for feeling this way. Having a stutter is difficult, and living in a world where atypicality is misunderstood is very stressful. People that don't stutter really don't understand the toll it takes; the fact that I have to really think out every word I'm saying, figure out swap-words, etc. The mental toll is tough and there's not an easy way around it; I really wish there was. But your speech therapist is correct, and positivity is a necessary component to how you need to view yourself, stutter included. I stutter almost everyday in meetings with executives, consultants, and people that work under me. Do I feel self-conscious when it happens? Of course. Do I wish it didn't happen and I didn't have people stare at me, or try to finish my sentence, or think I forgot someone's (or my own) name? Absolutely. But, what I've learned is that if you just power through it, ultimately, no one really gives a shit if you stutter. I've also learned that if I bring it up myself along the lines of "Forgive my stutter." (it really can be as simple as that) no one will bat an eye when it happens. And yes, that includes when I'm giving a presentation to my CEO. I would also like to recommend that if you aren't seeing a regular therapist, I would suggest one. I think everyone needs to see a therapist, even if you think you are the most well-adjusted person in the world. You might be surprised how that could change your outlook on a lot of things in life.
