Colleges are willing to discuss financial aid packages with families. Just saying "This isn't enough" is not going to get you anywhere. Bring facts, copies of income tax forms, proof of large medical expenses, forms that show losses, etc. to the discussion and be honest. If you have new grades, new test scores, or won an award bring those to the schools attention. There are still plenty of outside (non-college sponsored) scholarships available in late spring so keep looking and applying.
