Brew has kept you from being alone and lonely and has been an important part of your life for a long time, so of course it's natural to miss him right now and you will continue to for some time to come.
But! You will have PEOPLE around you now, and how cool is that! You are a very gregarious and sociable person, Kelsey, I think you are going to LOVE your new digs! You're going to be fine , and so is the Brewster. This is a new chapter for both of you and I have no doubt you are going to be very successful in it!

Remember, this is an answer to many prayers!
