Hi @Lirial @Rossana
I'm a teacher and I actually left the profession in 2023. Only to return to it 6 months later in a different state of Australia, but that's another story entirely.
I left for a number of reasons, but one of those reasons was the toxicity of my work environment and the lack of support. There were moments, where I was attacked by students, bullied by one particular staff member and made to feel as if I was inadequate in my job by leadership. One day, while home very unwell with COVID (I couldn't even walk to the toilet) the principal had my laptop delivered to my doorstep with the expectation that "I complete the tasks he'd emailed me from home," he needed them done that day.
It didn't take long before I hit pretty severe burnout and I needed to get out because...I had the sense that I wasn't going to survive my job. So, I did something extreme and I really don't recommend it...
I resigned from my job, which also meant that I lost my housing (I was living in a school house), I got rid of all of furniture and things and I drove myself and my dog across Australia to live with someone I had only met once before. It wasn't a positive experience.
I'm back teaching now, but I find myself in a position of questioning whether it's a good move for me. I'm also back in my home state, which I have no regrets about.
My advice is the same as what others have given you - document everything, so you have evidence that can back you up, set boundaries, and do what you need to do to take care of yourself.
