I lost all my Aura at school today

I lost all my Aura at school today I'm the president (head boy) of my school and today was republic day. I had to give a few commands for march past. Everything went smoothly when I had to give a command for the unveiling of the national flag. I stuttered hard. I don't know why. I stuttered so bad that I knew it was the end. Second when it was my turn to give the speech, I was saying is perfectly, but I stuttered a bit and I even missed a few words. This is the first time. I even came late to the school for the first time. Everyone were waiting for me. I had to run through the parents. It was so embarassing. My aura is in negative now. I don't wanna go to school now.
