I hate my job

I've had problems with my job for a while. But I always moved on from the problems somewhat, but now I'm getting to where I hate it again. I'm always dreading coming to work and dealing with the bs. I can't really quit because well I need a job, and it pays so good for it only being 3& 1/2 days.(and that it's only those days), and I got to choose what day I wanted off I chose Monday the same as my boyfriend so we can do things together since he works the weekends so that was nice to. I'm going back to school, but it'd be like another 5 years before I can get a job in that feild maybe 3. What can I do to get through this without quitting?
