Fantastic situation you're in - commitment- free, some money behind you, a profession, great skills and experience!
I took a great redundancy package, including £70k payout. It was gone in 2 years, because it was 2 years' salary.
I was 45, so the menopause had hit me and I didn't cope well.
You're years away from that.
You're also in the 'experienced and young' golden age for getting another job.
But.
It's frightening and hard being out of work.
I will never again trust an employer - multiple revenue streams is the ideal, no one thing you totally rely on.
My recommendation?
Go part time. So you still have income & current relevance on your CV - but you've gained the luxury of more time.
Use that time to set up your own business. Independent teaching, training and coaching are a great solo business move. Build it. It'll take time ...
Then when it's established and earning, take the huge leap and leave the teaching job.
Stay on great terms with employer & colleagues - your network is an asset.
Alternatively, look to leap into another part time role while you build your business.
Or polish up your CV and LinkedIn profile (LinkedIn is ESSENTIAL) and register with recruitment agencies and kick off the new year with a fresh start.
Whichever you choose, it's clear teaching as an employee no longer has your heart.
