Discouraged and stressed to the max.

So, ladies, I guess I'm just wanting to get some advice and vent a little. 
I want to start school in April so badly. I have been waiting to start school and am so ready. Online is NOT an option with the field I am entering. If I went to school full time I would go Tuesday-Saturday from 8:30-5:30 and I would be done within 12 months. If I go part time, I go Monday-Thursday 5:30-9:30 at night and it will take TWO YEARS. the reason I don't want to wait that long is because I'm struggling. I mean REALLY struggling. I can't do anything nice for myself or for anyone because I truly have no money to my name once the Bills are paid. I can't afford to treat myself to coffee with a friend or lunch out with friends or anything at all. I can't get a haircut, I can't afford to even buy myself some glasses since mine snapped in half. 
I am so stressed out and constantly worried and anxious and crying because I cannot continue to make next to no money while paying rent and other bills. 
I spoke to my boss, and she said she does not want to work with my school schedule if I go full time. She said it never works out and that she's tried with other girls and doesn't feel like dealing with it again. I'm so beyond stressed out and I'm trying so hard and all I want to do is succeed but every time I try, something is stopping me. I make minimum wage and have tried getting better jobs but never get a call back for an interview. I'm scared that I will have to choose between school or having a job and being able to pay for my home and car and bills. I'm just so stressed. Has anyone been in this position or something similar? How did you get through it? I would love some advice. Please be nice.
