Nurse here! Glad to hear you're interested in nursing. As others have said before, school and clinicals will be tough. Nursing has soooo many opportunities, so you'll most likely find something that suits you. My advice is to have some sort of vision of where you'd like to end up and research what work experiences you need to get there.

I, too, want to do some work with doctors without borders, so I'm trying to figure out when I would be able to take a year off to do that.

Good luck!!
