OK, Kit ... here's my advice:- there's a whole world outside the NHS. Bin it, then take a year out (travel the world, volunteer in something that appeals, write your memoirs
By the end of the year you'll have a few more ideas ... and who knows, after a year of refreshment, maybe you'll appreciate that being "on the tools" is a noble vocation after all!
And don't forget, there's always the "darkside"! Just make sure you don't screw up any pension rights you have, though.
