Rev I feel for ya somedays it seems like nothing goes right. But it sure sounds like you need a day at the spa. Staying home with the kids is a very hard thing to do. Anyone that says different does not have kids.
I am not to sure if you have family close or not but it looks like you need to ask for a favor and ship the kids to a family member for a couple of hours. And during that couple of hours take some time to your self.
