Finding Loans for College at 53?

I started college at 48 yrs old and it was an eye opener after 30 yrs of being out working. I borrowed money from the government and completed my associates degree, then started my bachelor degree. As the 3 years passed and I started my last year I got within 149 credits out of 180 needed for my BS degree. The classes got really hard for me during the last half of my 4th year and I failed 2 classes and had to re-take them. I got past those on re-do's but this caused me to hit my maximum with my loans, so the university asked me to take a leave until I found a way to be able to pay them.

It's been over a year now and almost 30 applications later and there is no money to be found. So after waiting until my 2 girls got grown and putting me last, is this it? I waited 30 years and now owe $60k on what would only be an associates degree because of my age, being permanently disabled and had to work twice as hard to teach myself what's simple to those just out of high school, like Microsoft word and even typing for that matter? I just wondered if anyone knew of something I might be missing for an avenue for additional funding? I can't imagine the government is OK with paying so much so far and not willing to help me so I can move on, but they have guidelines to follow. Thank you.
