Should I quit my job if it's making me cry and feel physically ill every day?

I'm going to quit my job but haven't decided if I'm going to simply stop going or put in my two weeks. I'm pretty sure I'll just stop going.

My job was amazing when I started a few years ago; the pay was never "great" but I stayed for the people. At one point I even stopped going to school because I became enthusiastic about moving up and shit.

There have been way too many negative changes in my department and I know it will never be the same. Morale has gone way down and my current manager treats everyone like shit. Once I started speaking up about certain issues, such as him shouting at me over me asking a simple fucking question (there were witnesses), he started going out of his way to write me up for menial shit that other people are constantly allowed to get away with. People on my team who call out three times a week have not even gone through disciplinary action.

It got to the point where I had to contact HR, which turned out to be a huge mistake because the HR manager is really good friends with my store manager. They pulled me into the office a few days ago and accused me of trying to stir shit up in the department and that several people reported me for allegedly making them uncomfortable by constantly trying to siphon information about my manager from them. I knew that was bullshit because everyone in my department is already on the verge of quitting and is tired of the politics and bullshit as well.

I don't get paid enough for this shit and I'm looking forward to going back to school full-time to finally finish my degree. It's going to be nice having less insomnia the nights before I know I have to be back there
