You shouldn’t worry! Your app looks very strong (good GPA, test score, course load, ECs, etc). Plus the fact that you are a caucasian living in the Midwest who is financially well off will not hurt you. Also looking at the things you’ve done while in high school you seem like a very driven and hardworking student. Good luck!!!
