I think I'm going to be homeless, is my "plan" unrealistic?

I hate the idea of a 19 year old girl staying in the mall at night alone. Not only do you not know who might be lurking about, but I'm sure there are security cameras all over the place and you might jeopardize your job when they find out. Surely there are people in your town who rent rooms. Renting a room is not the best option, but it sure beats the mall, and you'd have a place to bathe and probably kitchen privileges, at least. You probably would not have to put down any sort of security deposit, either. Any town big enough to have a mall would surely have public transportation, and if not, you could maybe carpool with someone or advertise that you need a ride to the mall at certain times. I know you're 19 and adventurous, and I do appreciate your independence, but the mall plan is a no-go.
