Give yourself the gift of peace and quiet today. It's not selfish to want to be by yourself -- it's healthy. You are in an inward phase of life, which will help you recharge your emotional batteries, center yourself and get better prepared to be there when the people you love need you. Be honest with your needs, and as long as you keep your people in the loop, they'll be cool with you pulling back from your social scene for a little while. Everyone needs a break once in a while!
