OP- before you commit to loans beyond the federally guaranteed amounts, it’s worth investing an hour or so to see if there are local “last dollar” scholarships that might be available to you. These are generally not for a lot of money ($1K or $2K is typical) but they are designed to bridge the gap between what you have gotten from the college and the government, and what you need.
Some will require a short essay (“how going to college will help me and my community”), others just a letter from a social worker, teacher, pastor, etc.
I know the gap between what you need and what you have seems insurmountable right now. But Google; see what comes up in your area. And yes- these are usually local, paid for by community groups for kids in the community.
And if your family isn’t connected to a social worker or pastor-- try the local Boys/Girls club or similar. They may have a “HS to College” club which provides mentoring and assistance for kids who attend- and the counselors and mentors at these programs for sure are aggressive at finding every last possible dollar for students who get accepted to college.
