Senior Year Jitters

I shake, I laugh nervously, My mother says she is so lucky, For I'm one of the few teenagers who likes school, So I try to tell her, it's not cool, I'm going to be at the top, So I m not on the mood for riddles For I have the Senior Year Jitters. Being in high school again for the 4th and last time I'm really getting too nervous to rhyme I'm hoping that by graduation I would have found a revelation That even though I try not to fiddle I still have the Senior Year Jitters.
