How to deal with exhaustion?

Kristen • 29.NY. Nursing student. In love with my best friend. 🌻❤️
I'm 22 and I work full time on top of being a full time student. This week I'm doing three extra shifts. I've worked every day this week. I worked 9am-3 this morning and I'm working 11pm-6:30 am with class at 10am and have to be back at work at 3pm. I have the shakes bad right now. Any tips on how to deal with this?
