Stop giving a fuck. I mean this. I stuttered awfully in school and still do somewhat. You dont need to defend yourself verbally. Those who would pick on you are weak as fuck they are very insecure and only do so because they think its low hanging fruit. Take that harmony and peace you found and embody it. So what some stupid humans make fun of you, you got this disability to learn to grow a thick skin that they cant get through. This post is deep you know you have a body but you are soul. Once they realize they cant get to you they will stop. Speak up in class raise your hand, show them that what's important is what you have to say, not how you say it. You will find your true friends, and those that would mock and laugh at someone with a disability, you wouldn't want them as friend anyway.
