Ihave created a character and background for my short story i am writing in language arts, can anyone shorten down my background for my character?

i wasn't always so shy. like any other child, i was happy, cheery, and i even made friends easily. i wish that was the case now; but for some reason, whenever i try to talk to someone else it feels like my throat is trying to crawl into my stomach. i only started to act like this after my parents died. i remember it vividly. it was a saturday night when i was 5, and i was doing my teeth when the house caught fire. i was on the second floor when i heard my mom screaming. i started to run towards her but stopped in my tracks when i saw the flames licking at the staircase. i backtracked towards my bedroom, and i climbed down the tree outside my window. i ran over to my neighbors' remembering what my dad told me to do in an emergency. call 911. it's all blurry after that. the fire engines came, the ambulance came, i remember sitting next to my dad in the back of an ambulance repeating " don't leave me" over and over again. they were in the hospital for a week before they died. after that, my aunt took me in. my life has been going okay so far. i still have nightmares that i'm stuck to the ground, and the fire creeps its way up the staircase engulfing me. i don't have anyone to talk to except for xavier, but he's a dragon. no-one else sees him or hears him, but that's okay because he's shy too. i have lots of drawings of him with his shimmering turquoise scales. sometimes i wish i could be like one of the heroes in my books. saving the city from monsters, but i'm content just settling with my life how it is now.
