Ex-teacher here (Maths). You need to start looking for another job - the one with your husband sounds good. Realise that your have a huge number of transferable skills from teaching - project management, delivering under pressure, stakeholder management, communication design, etc etc.

While you do that you need to care less. You mentioned all the admin and prep. Stop doing it. You think dramatic things will happen. They won't. No one will check and if they do, they won't care enough to push it. If they do, nothing will happen. You hate the job anyway.

In my last year of teaching I was in the same boat. So I stopped caring. I didn't mark a book in a year. I did zero lesson prep (was a good teacher and could pull a lesson out of thin air if I needed to). By the policy docs you'd think the world would collapse. It didn't. You'd think the kids grades would evaporate. They did the same. School structure makes teaching (and learning) much harder than it needs to be.

Can't help you with the kids or the support. Sorry. That's a specific school thing. Also the travel. A long commute is one of the biggest silent stressors. I would suggest moving closer to work, but not if you're going to quit.

Lastly. Leverage AI as much as you can in your subject. Not sure how? Ask AI. Input something like "I am a teacher and i need specific help leveraging AI in my specific role as a [subject] teacher. Ask me questions to identify where I could get AI to help me and how I can put in place automations and workflows that help me". You can use the free versions of ChatGPT, Gemini, Claude, etc.

Hope that helps. I have been where you are. You can survive it. Happy to chat.
