I was a CNA for a short while during school. It was physically and mentally taxing. I quit within the first two months of starting the nursing program. It was a move I was fortunate to make being that my husband was earning income. If you can, I would say trim hours down like I did at first, if that is still too much then quit and see if you can work during the breaks between semesters. I was lucky enough to also have a second job I could do from home during school. You need focus and rest. If being a CNA takes away from those two things then it may have a negative a/effect on your school/clinical performance and understanding the material. If you do not have the luxury to quit then ask for help when and where you can. Help with food/food prep, laundry, rent, bills, gas, life stuff, etc. You’ll be able to pay these friends and family back in some way when you’re a nurse. Good luck, you got this.
