It's desperately sad that you and so many others are being forced out of education because it has, as you say, ceased to be remotely about 'education', but simply ticking boxes for administrators and keeping kids off the street while their parents slave away at crappy jobs.
Have you thought about coaching/tutoring/therapy roles? I suspect that the most valuable work to be performed know is the remedial support for those being ground down by the education sausage machine. Provided their parents can afford such services, of course, because I presume there is very little provision by the state.
Good luck with it all - and well done for sticking at it for so long. When my mum retired from teaching 20 years ago at the end of her career, she had already spent the last 5 years complaining that it was no longer the role she wanted to perform in the classroom.
