Should I switch schools?

I currently attend a very tiny, all-girls school that enrolls students from grades 6-12. Recently, I’ve noticed that I haven’t been too happy at school, and I’m seriously thinking about switching to a different school in the fall. For starters, my school is just so tiny, and I really don’t feel like I connect with anyone there. The all-girls thing can also be hard to deal with sometimes (because you know how teen girls can be.) Sometimes I think that I’d be happier at a different school, but part of me doesn't want to leave. I really love my teachers at my current school, and it would be quite difficult for me to leave them. Any advice?
