em...what is the prompt? Or is there a prompt, I am a high school junior that are worry free of college apps so I don't know the format very well.
Studying abroad without the family was a real tragedy for me as 11 years old international student;
Do you really want to use the word tragedy? Since tragedy means more about incidents that are caused by outer forces, miserable maybe a good word choice?
Therefore, I never gave up and now I cross the line too far to give up.
You have build some really strong emotion there, use it, say like ...give up getting into college or something.
I hope those comments help, it look good other wise, at least way better than my writing =P good luck :D
