BY, I see where you are now – already away from home and looking for an Ivy.
I think your choices are
– large MO school – NY, Atlanta, Boston, LA. Each of them have strong communities and kollels where you may find a family that will help you stay strong.
– small yeshivos in same type of cities. They are often started by people who want same as you. In those places, they would know what quality secular education is and somewhat compete with those MO schools
– go back home and together with your parents organize your own education – possibly Jewish one in one place and general in another. Be creative – find partners for each of them. Say, one semester/year in a yeshiva, and one semester/year in general studies, plus summer. Tutors. Summer schools in colleges. One resource that I am using for my kids – online state schools. My older kids did this for just two last years and went to a mid-tier (online) college, having 4+ GPA and access to AP classes. Maybe more than 2 years would be needed. If your parents have time to engage with you, you can achieve a lot. My kids are saying that they are 2x more efficient when they don’t need to treck to school a t a certain time, can skip or repeat classes as they need. They are having less fun, but I don’t think that is what you are looking for.
