I am giving you the same advice I gave RJ Junior. The private school may offer you more scholarships but at the end of the day the tuition's higher. She ended up at the state school that will cost her 1/3 of the lovely private liberal arts school where they offered her a scholarship that amounted to 1/4 of the total tuition. Never, ever go into substantial debt for a private label.
I might also suggest that instead of pushing on at this point that you get a CNA, patient care tech, or MA certification (whichever will get you a job in a hospital). Then you can work for a minute and see if this is really where you want to invest your time and effort. You're 21. You're doing fine. There's no rush. And the odds are that in five years you'll be doing something else, and in 20 you may have a whole different career.
