C33 has a point, talk to our wife and be frank, I am sure she doesn't want you to feel empty and unhappy in your job. Aloow her to resist the change at first, but i am sure she will understand eventually.
I am on a verge of changing my carrer as well, similar story, except I am an academic, really dissilussioned with research and the whole system. I have been taking small steps and letting things to come to me in small steps as wll. And every time I want to rush things and make things happen NOW, I get overwhelmed and stuck. Probably not too good for manifesting.
Send me a msg if you need to talk - we can exchange notes
