Dental hygienist or RN???

Which would you say is easier & less stressful? In college which classes do you think is harder . Classes to be a dental hygienist or a RN? I know they both have good pay depending on where you live but I’d like to know more . Right now I’m doing RN so I have a few classes but they are so hard and stressful it makes me feel so dumb so I was thinking about switching to dental hygienist
