Everybody needs time off to recharge. I go spare if I don't have my down-time. I've been missing out on my exercise lately and I know I've been feeling the impact in other areas of my life, for one the house is a mess.

You need time off, even if you can escape for 15 mins in a bath, with the door closed, candles and some nice smelling stuff in there, just lay back and contemplate your navel. Have your partner kid-wrangle so you don't have little fingers sticking under the door looking for you.
