If you're still feeling as if your mind is a big fog bank and your emotions are hailstones, you might not be quite ready to face the usual demands you juggle from day to day, much less any extra responsibilities. Keep your cool if your partner volunteers your services for a fundraiser or your kids tumble in with hungry friends looking for dinner: remember that 'no' is a complete sentence. As soon as you can, try to escape to a quiet part of the house and lose yourself in a book. The diversion will take your mind off what's troubling you.
