It's such a strange feeling when they go because when they are home your life revolves around them. I watch netflix, exercise, go shopping, meet up with friends, tackle some project around the house, read of book. I also have a "list" of things I have always wanted to do that I can refer to. It takes some adjustment but you will learn to enjoy your down time. It's a time to rediscover exactly who you are as an individual and not just a "mom".
