My head is going to explode

I am a third year teacher. I have never had a full "normal" school year. Even with last year's craziness with hybrid teaching and covid prevention strategies like masks, distancing, and one-way hallways, this year is different. This year is different, but I can't quite nail down the reason. It feels like I have never had more on my plate. I do more administrative work and babysitting than I do teaching. My kids are tired. I'm tired. Everyone is tired and tired of each other and tired of the system sucking. There has to be a better way. I love teaching. I love my kids. I love teaching my kids and watching them learn. I hate being a teacher. Being a teacher is no longer just about teaching. It's almost become political, regardless of subject area. I have spent so much time, energy, and money to become a highly certified teacher. But now I want to quit. I want to leave teaching, because it feels like teaching is being constantly pushed to the end of my daily to-do list at school. I don't feel like a teacher anymore and I've only just started. I can't imagine how this year feels to a seasoned veteran teacher.
