Would I be mental to re-train in teaching after being a nurse?

[queenofwandss]

That really. I have been a nurse for 14 years and have done a few roles all in the community. I am a band 6.
Financially, I would have to wait before I can afford to retrain as a teacher, which is no bad thing because I need to think it through properly. When I have suggested this to colleagues and family most people say I am mad! Out of the frying pan into the fire and all that. Ideally I would like to teach English literature but maybe child development (nursing field) or textiles (my hobby).
Any words of wisdom?

I'm a trainee teacher and we only write lesson plans if we're being observed (once a week). Never write them otherwise and I've been teaching unqualified for a few years. None of us in our school write lesson plans unless being observed by HODs.
