Hi. I've been there. Speaking out loud in class felt like one of the worth things ever and that was in the 70s/80s. I know how you feel. ​ Regarding your friends, if they are your friends, ask them to ease up on the comments. Perhaps they think you are cool with it and joke with you about it. They are very likely to ease up once they find out how you feel about it. I found out I made things feel worse myself than most people were actually thinking. I'm sure others have said this and it might not be a huge help, but things do get better.
