I had yet another thought for you Jason... Have you considered starting your own business? I did that during a slump time at my husbands present job when he was sure he wanted out sooner rather than later... We bought a farm and began farming, using our higher earning potential to finance it.
We have just gotten to the point that Don could 'retire' to the farm as we're in a position to ramp up to replacing his income. That was a real possibility recently when he had surgery and it looked like he would not make it back before the end of his FMLA caused him to lose his job. Two things happened with that... We realized that we really do have the security of the farm and Don realized that he values his job and is not ready to leave it... More of the ebb and flow of burnout... right now the tide is out for him and he'd like to work a few more years.
Maybe start something small at home, involve family if you can (or make room for them when they are older) and just see where it goes... If it's something you are passionate about it may give you enough stress relief to see you happy again at work if just for the money... and if it takes off you could be the next Duck Commander
