Would you train to be a teacher?

[Iwantacareerchange]

I'm currently working as a paediatric nurse (27yrs) but the NHS is now in such dire straights with serious lack of staff both nurses and doctors and equipment/medication that I and most of my colleagues now genuinely fear a child on our ward will die and we will loose our registration. Also the NHS is being broken down and privatised, lots of areas have been taken over by profit making companies this depresses me money is coming before the health needs of our children. I took a career break when my children were little and have a good class degree in area that apparently there is a serious significant teacher shortage and "Get into teaching" are always emailing me. Today I spoke to them and have arranged various visits to schools etc to see what I think.
So the 64 million $ question would you retrain as a secondary school teacher?

Having been a teacher before having my children and now watching as my colleagues and friends struggle on a daily basis to reach the high standards expected of them - they're all broken; in spirit, mentally, emotionally... in all honesty, the education system today is not the one I joined a decade ago. If you feel demoralised by your current job, if you feel grated by the injustice of the institution that is the NHS - you'll feel very similar in the education system.

No. No. No.
I'm supply.
It's the only way I can do it. I don't know how people do it full time any more...
