I feel like you owe it to yourself as a distinct and sentient individual, with free will and arguably boundless potential, to remove yourself from the restrictive expectations of your parents. The challenge they will face is that they have succeeded, if you are happy - but that is not your burden to carry. Let them work that out; instead, embrace the idea of success that is most true to yourself - not one, I stress, that is any less intellectually and physically rigorous than something your parents may ordain (more, even), but one that objectively recognizes the immense efforts you have put in - without accurate and genuine benchmarks, and without a legitimate reward system, I fear you, as a person - may be limited.
You know you're successful. Embrace it. Don't let some admissions committee tell you you're not, and don't let your parents say so either - they have their own challenge to face.
