Bound to Death (Creepypasta X Fem! Y/N)

This story is gonna be a female y/n (cause I'm a girl and don't know how to write as a guy). This will also have my health conditions in it cause I think that would be fun and why not! This is my first time writing something like this so let me know any suggestions, have a fantastic rest of your day!!

Your childhood wasn't awful but it wasn't the best by any means. Well until something happened, you felt off you couldn't put your finger on it, it wasn't fear or anxiety but you heart was always racing. After months of convincing your parents to take you to the cardiologist they make you an appointment an you hear the worst news of your life.
