We have all been there and I can definitely empathize with this story. When I was thirteen, I was teased about my nose, which made life at school unbearable. The good thing is -- everything changed when I got into high school. You have written a very good story, here, and apart from a few typos, it is very impressive.
I really enjoyed this. As someone who was "the awkward kid with the glasses" as a child, I can totally relate to Erica. You write very well for someone your age- there's a few mistakes but overall the story is descriptive and poignant. I'm impressed. :)
