You are entering a very contemplative time in your life, so be open to your moods and follow them. Any urge you have to turn your thoughts inward might distance you from your friends a little bit, but if you keep communication open, you can get the room you need without making anyone worry or feel shut out. Feel free to ignore the external world for a while (or for at least today) and focus your energy on getting centered in your own mind. Take all the time you need.
