As an international student you shouldn’t have expected any financial aid from public universities – to which you applied. That’s not how higher education works in America. I’m sorry to say that you either were misinformed - or underinformed. You can search for “large corporate scholarships” (I’m not sure they exist, by the way) to help you, or you can do what most international students do: go to school in their home country, or take a gap year, and reapply, more strategically the second time around.
