So I start school next week and I'm kind of nervous about it. My voice cracks when Im nervous so that going to be a problem since EVERY teacher makes you introduce yourself in front of the whole class. Even if they don't ask me to introduce myself, they'll start asking me questions. My voice has cracked in front of the whole class before several time. I'm not really nervous about school, just the voice crack. It sucks completes ass. Any tips or methods to prevent my voice from cracking? I would really appreciate it. Thanks
