This thread has become piled high with self-help advice already, and none of us know whether our advice will help any with your own situation, but here's another take; make the best of one advantage you have, which is an endpoint. Pick a date and say to yourself (and probably also your wife), "on that day, I'm out of this shit job." Maybe with the uncertainty of selling you can't pick an actual day now, but do so as soon as you can, or say "at most X days after the sale." You know you probably aren't going to just quit outright, since the stakes are too high, but if each day is part of a process towards eventual quitting, that'll give it a bit more meaning. But also, for goodness' sake, take a vacation. The office is going to have to get used to your not being around eventually, why not practice now?
