Should I quit my job?

So I have been debating this for like a month now. I started this job at QT around September. When they hired me I told them I needed a minimum of 35 hours a week, but so far I only make 28 hours a week. I get paid weekly and I only get paid a little over 200 every week. I am attending college at the same time, so I use up a lot of gas money. I spend about 60 dollars a week in gas money alone. I have bills to pay, groceries to by, and school supplies. I do not have any fafsa, because it was easier and cheaper to just pay out of pocket. I am just not making enough money. I tried asking my managers to give me more hours, but they say that it’s not due-able. Everyone I work with treats me like I’m stupid, and it gets really annoying and frustrating. When I try to ask the managers for advice or help they just treat me the same way. They always tell me I need to do better, and that I’m bad for the store. Even though I’m one of the fewest new people that have gotten a 100% on every audit that they have conducted at my store (Which is every week). I know you won’t always like your job, and that’s life. But I just truly do feel like I hate this job. I always feel belittled, I’m not getting paid enough to support my means of living, and I can always find a new job. I have already talked to my boyfriend that I live with about it and he agreed that we would be financially ok for me to be out of a job for a little while. However, I also feel bad quitting my job on my boyfriend. I know I’m not a lazy bum, and I know I will get a new job, but I can’t help but to feel stressed about the whole situation. There are so many thoughts and scenarios running through my head, I just can’t think straight about the situation sometimes. So I am asking you guys for some help and advice. What do you think I should do? Or what would you do if you were in my situation?
