I am in a different advanced practice specialty, not NP, but, when I returned to grad school (MSN), I was able to get some funding from a student loan/scholarship
program offered by my state (to increase the number of nurses and STEM professionals in the state) and from a national, competitive scholarship program. I worked part-time to cover my living costs during school, and I took out student loans (federal loans, not private) to cover the rest of the cost. I took out no more in loans than absolutely necessary, and I lived as cheaply as possible in school (embrace the "starving student" lifestyle!
I didn't get any kind of employer assistance with repaying my loans, but I hadn't expected any and had no difficulty making my loan payments over the ten-year repayment period. I consider it money well spent and a worthwhile investment in my career. The scholarship from my state could be "worked off" by working in my state after I finished my degree, which I did; if I had not worked in the state, I would have had to pay back the money.
I would encourage you, also to embrace the "starving student" lifestyle and not take out any more in loans that absolutely necessary. As the dean of the law school a former boyfriend of mine attended used to say to the law students, cautioning them about excessive spending while in school and student loans, "If you live like a lawyer while you're a student, you'll be living like a student when you're a lawyer."
Best wishes for your journey!
