I quit my job without two weeks notice

I’m 17 and I’m finishing out my senior year. School starts back on Monday and I just had this feeling of anxiety. I failed one of my classes last semester. I work evening/night shift I get off around 10 pm every night and I don’t have a car so my parents have to pick me up and drop me off.

Anyways I just quit my job today because I started freaking out about my grades I feel like I have no time to study or get homework done after school because I’m always working. My parents told me to take a break and focus on school. So I literally just called and quit today.

I feel really guilty for leaving my coworkers with no one to cover my shifts but I can’t do it anymore. I’m mentally drained and I’m scared to go pick up my check because my other manager is not an understanding person. I just don’t want to get cursed out and ughhhhh
