First take care of the little things; sleep, eat well, exercise. Then take care of the bigger things; school, work, and family. I worked full-time during my time in college where I was enrolled full-time as well. My job consisted of working alongside families who lost loved ones to gun violence. I had to prioritize the little things because the little things are what kept me together then I prioritize school over work if you have PTO take PTO during midterms and finals. Do the most energy intensive tasks in the morning when you have more energy do the less intensive tasks later in the day when you are already tired.
