I use to think that about myself, that I'm weak and a coward because of comments like these from close people. But once I thought about my daily struggle, this struggle that no one can see, even in small things , like ordering food, people that don't stutter don't get the amount of anxiety we get, that's why I think that we are fucking strong as hell, we can put up with so much shit and we're still moving forward. On another note, If I could give you a tip, it's not a cure, it's just something that helps a lot, well, at least for me. You got to train talking in a affirmative way. It sound stupid, but just give it a try. Get any text online and read out loud putting emphasis in the "syllable tonic" ( I don't know if this is right in English, not my native language , sry ) of each word, you can use your hand to help in the beginning, when you train a lot it becomes second nature. For example, I'm getting paid to a graduate program in my country, but in exchange I got teach undergrads, when I first heard this I almost died. Since I never got any results with speech therapy I got in a oratory course, even though most of the students don't stutter , they're just there to enhance their public speaking abilities, I really got something out of this with this technique. Just giving you a idea out of the speech therapy sphere. Again, it's not that I'm cured, but my classes were not the shit experience I was thinking that would happen. Lastly, this technique is perfect for speaking in public, but if you're having a informal conversation with friends you can't talk like that, it will look like you're pissed or arguing. But this will go nice on a work phone call for example.
