my first short story based off a true event.. tell me how it was and if you can help me in anyway possible you can do so. truly appreciated!!

12:20 out with the unorthodox full moon right above me, walking over to the park with these unbearable thoughts of dread and sorrow heading to the swings, as i sit on the swings something didn't feel right its exceedingly cold outside and I'm sitting in my cold sweat, i looked over and the swing was moving by its self, which was utterly strange considering i couldn't feel a breeze to save my life. at first i grew fond of being in someone else s presence but then it hit me i had this hideous disturbing feeling which grew unbearable, I had to leave. Now as i get off the swing and am walking down the street i kept having this explainable feeling someone is watching and or following me, I look back not anything in sight. I'm walking back with this uneasy and restless feeling until i make it back inside. I still wonder who was in my presence, it felt like it was a girl between the age of 11-16 it seemed very playful, just another unguided and lost spirit like me but she had much more pain then i had ever imagined.. Who Was This?
