Personally, I think the best thing to do in that situation is simply walk out (if you've got enough money saved up, worry about finding a new job afterwards; if not, find a new job but don't tell your boss).

Don't bother handing in your notice officially, forget about working the notice period - just drop what you're doing, stand up, say "Fuck this - I quit" and walk. It reminds you, and perhaps even more importantly your boss, that your job is not who you are and your employer does not own you.

This is a bit metaphysical but go to a place you enjoy; a garden spot, a place in the woods, a lake shore or ocean side, creek, stream or river. Sit quietly a moment and absorb the peacefulness, close your eyes and think; "I will no longer allow my energy to sucked from me by - name the person(s), place or situation." Repeat 3 times. Then return to work.

One of the hardest things to do is this....periodically, try to fall in love with your job again...the way you did at the beginning. And if that's impossible...begin making lists of precisely what you want and need in your NEW job! Do NOT be one of those people who ''lead lives of quiet desperation." You deserve better!

Change jobs or retire !

It must be time to look for something new!
