Hypothetically speaking if you were to pick one of the two to go into as a field. Which would you?

I'm asking because I'm currently going to school to get my high school diploma "There's a long personal story as to why I don't have it already." and I'm confident that I'll have this done in a few months, so I've been on the fence about continuing school to either get my cna and then work to getting my nurses degree. Or, the other direction and do emt work, or emergency dispatcher.

Any of them I'm interested in getting into because taking care and helping people has always been my interest career wise. I just like to see other peoples opinions.
