i would say quit your job but have a  job that you can move into so that you still make money a less stressful and tiring one for a little while

I'd say stick with it a little bit. Its easier to get another job if your currently in one. Just apply for a job with fewer hours and then move into that job. Just pulling out of work and coming to a dead stop can make getting back into work harder later.

You could perhaps ask your employer to maybe lessen your hours, I'm pretty sure an other employ wouldn't mind taking up some extra hours of work for more pay.

I agree with the above, I've been in a similar situation before now - but applying for jobs from a position of employment makes you a stronger candidate (generally speaking, employers like to see commitment, even if you are committed to something less than ideal). It also means that your income doesn't dry up while looking for work, which (depending on the jobs) can make it difficult to attend interviews.

thanks guys ill be looking around during the fall its just these late nights been killing me XD wich messes up my sleeping routine.
