Am I right in this?

At the beginning of this year, at community college, I worked 5 days a week, 8 hours a day, night to morning, then because of the lack of getting enough sleep and only been able to focus on 2 out of 4 of my classes, I had to transfer to the part-time shift at my job. Months later, after I transferred to part-time, I transferred to a university and had to pay my tuition fee. When I got my tuition fee, i realized that the money I'm making right now isn't going to help me pay future tuition fees. So now I'm trying to go back working full-time again. That means I'll be working my old times again, and it'll stress me out like last time. I think taking 2 classes at my university will ease the stress. Am I right or wrong?
