Take the gap year.
If you have a place to live in the US, move here, get a job, get readjusted to life in the US, retake your SAT/ACT to try to raise the score, and apply to a new set of colleges and universities that are affordable. Do not take any classes for credit so as to protect your freshman applicant status.
Go read through the thread on Automatic Full Tuition and Full Ride scholarships that is at the top if the financial aid forum. Some of those will change for next year, but many won’t. If your grades and test score match any of those scholarships, you will get that money.
Hang in there.
