I am going to have a speech at school too, but it's only for the teacher (don't ask me why, she said that it was the best thing to do because some classm8s don't want to talk in front of everyone) so I will probably talk about something else, if it was in front of everyone maybe... But I think you should do it, if you represent it in a good way people will not think about it in a bad way and people will respect you for telling your secrets to them, I have gained some respect because I am open about it and not embarresd.
