I'm afraid to walk at class night what should I do ?

Class night is today. Earlier today some students received awards and we were seated in order (A to Z). The lady on stage told us we would come back today at 7pm for the program. I am so nervous, I do not want to walk on stage or slip, I just don't want to get out of my seat. I shouldn't get anything for accomplishments b/c my grades are horrible. But I believe they will give us bags for all students. What I'm trying to aks is what usually happens at class night ? I'm very shy so, people know that I am shy and I have no friends at school.
