Which one is less stressful and less hours? Rn, nurse practitioner, or pharmacist?

I would love to be an pharmacist but I don't think I can because I suck at math. So maybe I might become a Rn or a nurse practitioner . Which one has better hours and less stressful? Any info will help. If you are an nurse that would be even more helpful and you can also tell me your typical hours and day. please
