I would urge you to get the degree (and more importantly the knowledge that should come with it).
Do you know if you qualify for financial aid? Find our by applying at

Here is my biggest concern....in this day and age there is NO NEED to take on significant student debt. Student loans are the modern Siren call...and they can dash your financial future before you start. There are other ways...find one of them.
The simplest is to start at the website above, see what if anything you qualify for. That link is the Government website where just about everyone begins their financial aid / college journey. A full Pell grant (which is what you are hoping for...sort of) will pay up to $5600/year and it never needs to be repaid...it a grant. That amount is just about enough money for many state degree programs and it is definitely enough to nearly cover the full cost of some reputable online programs like this one:

WGU has a cool model. you pay for access over a period of time. For $2500 you get 6 months...you can complete as many courses as you want/can in that period. So if a class is easy for you, you can breeze through in a few weeks, if it's more difficult, you can take your time. A full year is only $5000 and that includes all books and study material.
Your local Community College is another great place to start...and is likely very affordable. If they are not a good bargain, you might consider an out of state affordable option. New Mexico for example has some incredibly cheap community colleges and universities. NMJC for example will take federal financial aid and 12-15 credit hours (that's full time) only runs about $1200/semester.

NMJC is a bargain even if you pay out of pocket.
I can actually talk about this all day, alternative higher education is my hobby. PM me if you like, I'd be happy to discuss it with you.
Remember these two things.....
TAKE ON NO SIGNIFICANT DEBT (really, take on NO debt...there is no need)
Choose a REGIONALLY accredited college (accept no other accreditation) All of your state schools, Harvard, Yale.....those guys are all Regionally accredited.
