Struggling with whether to quit job?

I am busy, like so busy. And it's not fun. 6th form and uni applications, medicine admissions tests and interviews and then my job as well. I'm managing but I can't help feel I'd be having a much easier time of it if I quit. And I'm only going to get busier as the year goes on, my mock revision is already lacking.

But I kind of do need the money. I have to pay for my own gym membership (which I don't want to quit), and phone and bus pass and lunches. And I will have to have some money saved for uni too. I have got savings, but I feel like they'll be 90% gone by June when I can start working again, assuming I can even get a summer job.

I'd also feel really bad about leaving just before Christmas, I have to give 4 weeks notice so realistically I won't be leaving until the end of November really.

I don't know, I'm really conflicted, It's objectively a good job to have. Pretty close to where I live, pays really really well 9.50/hr. Co-workers are all nice people. But it seriously drains me, even though I only do 2 6-hour nights a week. I finish at 11 for one. But even the job itself. I don't know why, my last job never left me feeling like this.

I don't know, anyone got advice?

Have consider swapping your job to weekends if it easier to do this....!!! Do either long day on Saturday or a Sunday and concertrate the week days on everything else till next summer and then go back and work extra days etc...

Yeah I've tried. Also tried cutting down my hours a bit but no. it's because I'm a) the youngest person there, like by far. The next youngest is about 30 and most are in their 40s. and b) I think I'm the only one there without kids. So they don't let me do any days on the weekend, I do work Saturday night, and then a weeknight from 5 until 11
