If you did not get a bachelors (strong assumption you did no such thing) fafsa can offer pel-grant To some extent even though it's a "graduate" program. Should this be true or not you would had to file your taxes NOT as a dependant to even get a descent amount unless your folks are making poverty threshold income.
Either way, you'll definitely get your fed loans out of this to pay for school....what I don't understand is why you turned down public school for private...understand 160k in tuition is what you'll pay not counting book/lab fees, rent, food, utilities, etc. strong low assumption your food/rent/utilities a yr are very modest (beans n rice) so I'd say 36k over four years plus your 160k (then again want cable? Fun now and then? Visits home?) and good 'ol health insurance will put you over $200,000 in LOANS for a job that will be half that salary (roughly 33% income to taxes of course, but let's be nice and say 25%).
Max 401k, get best health insurance and live frugally, you'll find out your living on lower free-moving income than others not offiliated in healthcare...very very small income with no plan and paying interest over years so you'll pay nearly $500,000 to debt should you pay minimum (don't get me started on cars and mortgage)..
My point? Come in with a plan financially and prepare for saturation. I hope you did not choose prestige over cheaper education with same degree. Good career choice if you have a plan (GI Bill, vet in-state residency to any public school, book and home stipend tax free and direct deposit to checking account, and choice of job placement when out...no regrets here when the time comes).
