When I run away, I run to a very secluded cabin in the Smokies that has a jacuzzi, fireplace and a wonderful hot tub. There's no one to be seen for miles. After about 4 days alone and staring up at the stars while soaking in the hot tub I gain my equilibrium back. It sounds like you badly need a break. You might say you can't afford it money wise or time wise but what's going to happen if you breakdown or burn out? You could plan a small 2 day trip to see if that helps.

I'm sorry you're having such a tough time. Sending big hugs.
