Did you try to apply for federal funding through the FAFSA to see what federal student loans and grants you qualify for? When I was in college I got grants in addition to the loans even though I had 2 working parents. It is based on salary/income/need. Also, check with the school or schools you are applying to and see if they have any scholarships or grants with separate applications you can apply for. Also, depending on your state, there are loan forgiveness programs where there is a high need for nurses (if that is what you are going for)-- maybe check into that for california as well (I know they have them for nursing and also teachers in some places). For other types of grants, talk to the financial aid office of the school/s you are applying to -- they keep files on that stuff and also comb the internet BUT be careful -- do not PAY money to get money. Applications should be free.
Best wishes!
