The Shy Girl

My breath is uneven, rigid, and it's coming out fast and shallow. I knew I made a big mistake but I never thought I would end up here. My legs turned to jello and gave out beneath me. Now why couldn't I be more athletic? Darn my sweet tooth! I knew all that junk food would catch up on me. That's when I saw a shadow cast over me, and I knew my pursuer was right above. I have nowhere left to run.
I personally can't find any words to describe this book. So you're just gonna have to read this short story in order to find out what its about.
(P.s I dont own the picture for the cover. So the credits go to the original owner. Oh and it's a coincidence if this story is similar to any others. )
