Should I just go primary?

Hi, I'm 19, and I started subbing when I was 18 just after graduating. I usually did middle school because my little sister was there and I'd be able to drive her there in the mornings to avoid kids on her bus.

But I've been receiving some awful comments from students regarding my appearance that almost border sexual harassment. I've written them up or told them to stop directly, but they either treat it as a joke or the school does nothing about it 🤷

I'm thinking about just doing primary schools. I've been a little put off from doing it because they need some extra hand-holding compared to secondary, but honestly I might have to, and some advice would be great!
