first of all calm down because you being nervous isn't really helping right now. if you have a friend or someone you know go to school with them as you talk. if you can't talk to anyone else have comfortable music before you enter school it always helps me when I'm nervous and just try to read harder don't worry about the past because right now you can change it all the best lovely and remember you are beautiful, you look beautiful and you can do whatever you put your mind to
