Should I be nervous?

So I’m a freshman (in high school), and my boyfriend is a senior (in high school). We’ve been dating for a couple months and all my friends are super supportive. The only thing is , we go to a super small school (400 kids) and like most people know, and from what I can tell are kind of judgmental about it. We’re planning on going to turnabout together, but I’m kind of nervous because it’s not a super coupley thing at our school, and I’m worried people will judge and make comments. Should I be worried? Any advice for what to do?
