Brooo I literally deal with the same thing. Like you can just feel the whole vibe change once they see that. Then they start saying stuff in a softer voice like I’m a kid or something, like bitch I’m not stupid, I just have a stutter. I hate when I’ll be trying to explain that to people and they’re like,”Well…..it’s okay to learn a little slower than others.” Like did you not just hear me tell you that that I’m smart but people think I’m dumb because of my stutter or judge/single me out. That’s why I have social anxiety and depression now because of peoples reactions to it in the past.
