Help return to school for another chance to do better

Well I know this probably isn’t serious for everyone else. But I’m just trying to raise the money to return back to school. I’ve had a very rough year academically, physically and mentally, I’m doing a lot better. I joined the Virginia national guard hoping I can save the money to return back to school. I ended paying 16,800 back by a private loan. Which it was already sent up to the general attorney office. During this time I was at basic training. So I wasn’t able to pay some of it all then. So I now have a remaining balance of $4,053. Anything would be grateful appreciated 🙏🏾
