First off I want to say I'm so sorry. High school is hellish for everyone, but especially for people who stutter. When I was in high school we'd go around the class and each person had to read a paragraph from whatever book we were studying at the time and when it came to my turn, stuttering would ensue. I'd hear kids whispering, imitating me. Laughing. Even my friends would mimic me and: it hurt. You need to tell your friends very firmly to stop the next time they mimic you. And if they don't stop, you need new friends. I know how hard it is to meet new people but there may be someone just like you at your school also looking for a friend. I've stuttered since I first learned to speak and my parents would get into arguments about whether to send me to speech therapy or not. Both teachers and parents can be really insensitive about things they don't understand. It's definitely not something you can just "get over." As for the suicidality, I had those feelings too. For a lot of different reasons, but stuttering was one of them. If you'd like to talk about it, let me know. I've battled with depression my entire life but I have a good handle on it now. I wish you the best and: just because a stutter may be lifelong, high school won't be. You'll be out of there before you know it. People are generally nicer when they're not hormonal teens :)
