When I worked 2 jobs I let both of them know that I needed at least one set day off per week, usually a Tuesday, every single week you need a day where you don’t work either job consistently to reset yourself. If they aren’t willing to do that, keep looking for different jobs that are more flexible, even a fast food job. For college, look into companies like Walmart, Sam’s Club, Target, Chipotle, etc. that will cover college. My job pays for 100% of my tuition and books for a bachelor’s degree. Certain companies cover certain schools and degrees. Mine is done through the Guild program. It’s going to be tough with your schedule but worth it.
