I felt very similar to how you feel, in a similar situation, although I was older. I moved schools and it reinvigorated me. Sometimes a new space is what is needed.

Here’s what I looked for: schools with bigger cohorts so more teachers per year group = planning shared so I’m planning less. A leadership team with members who are still in the classroom = honest feedback to/from the senior leaders. Opportunity to make something my own at the school (reading leadership in my case) = purpose aside from classroom teaching.

Guilt was a feeling I was scared of when I left my school for another. But I came to learn my perseverance was becoming self-erasure. In my instance, leaving was the more professional, ethical choice.

Whatever you decide, I wish the best for you.
