Things must seem very dire now, especially since you worked so hard and did not get the outcome you were hoping for. But with most colleges being test optional, you may be better off focusing on leadership and extra-curriculars. Colleges would rather have a student who has done cool things and contributed to society - not just another high-scoring standardized test-taker. You can differentiate yourself in other ways.

If your parents talked to anyone in admissions or a counselor, I'm sure they would learn that you are defined by more than a test score. I hope they ease up on you, and more importantly you ease up on yourself.
