I wanna quit my job, but then I won't have a job

I wanna quit my job, but then I won't have a job. I don't have a car, I'm 22, I live in an apartment. I make enough to cover rent and my car payment that I am supposed to start paying in a few weeks. I've been working at this job for 3 years and I am so tired of going. It's so boring, it takes up most of my time. I live paycheck to paycheck, I have nothing in savings, all I think about is saving. I am emotionally dead to the world besides a few people I care about. I am so fucking sick of it and I don't know what to do. I want to quit so badly, but I'm stuck. I am so sick of this.
