Venting

In school today we're starting realistic fiction stories and i couldn't think of a good story so i decided to write a day in my life or a week maybe. Just to show I feel, and see what people would think. The only problem is i'm scared that my teacher will realize it's me that im writing about. I thought i could just say (if she even realized and confronted me about it) "my story is just if there was a girl at our school who happened to have all these problems" and if she asks for more i could also say "these things don't really bother me personally but i could see how someone could be bothered by them" i also didn't want people to be like "ohh is she depressed" that would just make me mad.
