Tired of my mom

The title might sound childish but oh well, it says rant and that's what I shall do. My mama is a very inconsistent person and she usually goes back on her word. Yet, every time she says she's going to do something, I believe it'll get done and when the time comes, it doesn't get done. Since I graduated high school, she's told me that I would get a car and an apartment my senior year of college. Here I am now, senior, dual major in chemistry and political science, high GPA. I've done everything she's ever asked me to do, no matter how stupid it was. I ended up getting myself my apartment because she dropped the ball and she said she would work on the car. Now, I have an apartment, she just dropped the ball on the car, I just found out through an email from my school that the money I've been helping put towards my tuition and her half of it hasn't been going to the school, and therefore until it's paid, I can't get registered in class. I have a house 30 minutes away from school with no way to get back and forth to school, which I've just been kicked out because my parent has taken my school money and has done only God knows what with it. And whats pissing me off is the fact that she doesn't care. I was supposed to get a car a little over a year ago, and with that being the case, I got a job, ended up not getting the car, and then I had to depend on friends to take me back and forth to work. Her attitude is that since they did it before they'll do it again. Meaning she expects them to drive 30 mins from school to get me, drive back, and then drive to drop me off back at home and drive themselves back to pick up her slack. I could have just stayed on campus this year, but she kept telling me not to apply because when I get my apartment and not be on campus I would have an additional charge. So now, she's blaming the fact that I don't have a job, in which she scheduled this month and a half long trip across the nation and since I got home from school mid May and left the first of July, nobody would hire me to work only a month. Like it's stupid. Now I'm just like, I may have to take off my senior year of college because she been taking my school money, get a job, I have no way back and forth if I get a job, my refund from school is supposed to be what's paying for the apartment, but now that I have a balance from the last year and a half (because the school money never made it to school), they're going to take that money from the refund. I'm just stuck.
