Gotta find a balance

So I have been finding that staying busy helps me to stay in a better mood. The only problem is sometimes I get so busy that I end up exhausted. I enjoy staying home with the kids and just having a lazy day but then sometimes those days turn into depressed days. On the other hand, I don't want to be living out of my car. So my goal right now is staying just busy enough without going over. Things should slow down soon with my church calling so that will help a ton. Anyone have any advice on finding a balance? (If anyone is reading this yet!)
