We are in the same boat. And to top it off, our whole family got ringworm from an adopted kitten and so having to go through that hassle, and out car just broken down for the 10th time, he's been working on it for 3 days $1000 later and he's hauling it to a lot right now to try and trade it in for parts, plus, he's stressed at work and family stuff too.
So, in two weeks, we are going camping and visiting friends/family we haven't seen in a long time over a weekend. Take a few days off, rejuvenate, look for solutions to problems. There's go to be something cheap and in the area that you can do to get away.
As for during the week, we bake cookies, and watch a family movie, have family scripture time and prayer. Then we stay up late talking and hanging out. Somehow, it helps us decompress a little. We also make stuff, like we like to make puppets together or work in the garden. Just try and do something every few days for a couple of hours that you all enjoy. One thing we did a few months back, is we went to a concert. It wasn't a huge expensive one, but it was so fun.
