First sentence sounds awkward, you should try to change it. Maybe to change the word "ball". Also try to make it stronger.
much like my life would soon become as my parents gave up.
I don't know want you mean here!
Millie had to fight for herself much like I fought and still am fighting the battles in my day to day life.
Maybe be more specific why your everyday is a battle. Do you suffer an illness? do you have family problems?... how that experience helped you to be stronger?
I think you have a good topic, but try to improve the way you describe it, make it more fluent and soft, and more understandable to the reader.
Good luck
