Giggles -Creepypasta OC

This is the backstory of my Creepypasta OC, named Giggles. It is not completely intended to be creepy or terrifying, though it contains gore and violence. I intended to make it a good, logical backstory for my OC. The story isn't perfect, it needs some improvement here and there, some parts are a little vague and other parts somewhat rushed. And of course, the story itself isn't perfect. I tried to make her reason to go insane as logical and understandable as possible and avoided making a Mary Sue as much as possible (and I personally think I did pretty well on that one). If you have any advices to make it better, or point the parts that really need improvement out to me, I would really appreciate it if you would tell me. Anyway, if you decide to read it, enjoy c:

Giggles is 14 year old and has lived in the circus for almost her whole life. As a small child, she was thrown onto the streets, due to her strange appearance, which was caused by a genetic mutation. She was saved by being adopted into the circus. Over the years, she has learned agility, flexibility and more circus skills. She's quite happy and smiles a lot. That was, until she had a close-death experience. Suddenly, things seemed uncertain, death was always close and so, Giggles her life changed in a way that was irreversible.
