I know how you feel bro and I'm sorry you're going through this. The truth is that you actually have to accept just the way you are. Just yesterday I arrived late to class and I had to explain myself to the professor. I stuttered in front of the whole class. Some classmates laughed at me. I also saw the teacher smirking a bit because I don't think he's ever heard me stutter before. What else could I've done? That's how I talk, and there's no solution for it. Also, yes, this stutter will stay with us forever. You have to think about all the bad things you've been through because of your stutter and make sure that you will get through any obstacle that gets in your way. Remember when I told you about those people laughing at me in class? Well, I just say to myself: "Okay, I'm in class with other teens who are really, really stupid because they're literal kids and the teacher is an asshole for smirking." Focus on things you can actually change, especially your self-confidence. Not just with the way you talk, but also with your looks, your style... whatever YOU think you can change for the better! Our stutter won't change, it will only get a little bit better with more self-confidence. Stay strong. I know it's hard to ignore people's jokes, comments or laughs, but I'm sure that you and every single person who stutters can handle anything.
