I feel you. Just yesterday I was thinking about the first time I got to talk in front of the whole class on my first year in high school, like, 15 years ago. I remember I couldn’t speak one single word without stuttering. Until these days I remember how stupid I felt on that event . I’ve also got a lot of nicknames along the way and had people making these kinds of “”jokes”, discrediting my opinions, thinking I was retarded. What I did to make things better was getting really smart. I know it sounds arrogant or something, but it is what it is. The world tends to think people with stuttering issues are mentally inferior and not capable of anything. So I still study and work twice as hard to become even more proficient in my career and everything that I like. It’s has worked so far. And the reason is not only being acknowledged by others, but also the confidence boost and the fact that I don’t care about these kind of comments anymore. Never let anyone bring you down or get sad because of stupid people in the world. Specially the ones you don’t know. Work on yourself, on your confidence and the next time someone makes fun of you (it will happen) you will be a lot more prepared. Best regards.
