You do realize that living in an apartment is cheaper than living in a dorm? Let me explain. Obviously you seem to be living in a rather expensive apartment complex. You will have to go to the low end apartments, which may not even necessarily mean you have to go to a "rough" neighborhood, but it will certainly be outside of the confines of solely university students. The more roommates you have, the cheaper things are going to get. At the moment, I have one roommate and I pay $380 a month for rent. $430 with all other costs included. Meal plans are also a rip-off. University food, no matter where it is, is always going to be less healthy then buying groceries. Just like restaurants, university food will be packed with sodium, all while containing fewer than ideal nutrients and being overtly processed. Nutrition is very important while putting your body through lots of stress. Not only that, but I was unable to achieve my caloric needs while lifting weights in the gym on my university plan. As a medical student, you're not going to have time to revolve your schedule around the dining hall.
Long story short, do not live in dorms -_-
*Edit: meal plans are also a rip-off. By not getting a meal plan, I was able to recieve 110/week for groceries for an entire year at the cost of a meal plan for 9 months. $110 dollars goes a long way at Walmart and then Harris Teeter (or any quality grocer) for produce and meats. If I can eat 2800 calories a day off that amount of money, then you, as a girl, can surely eat for far less.
