I totally know what you mean. Whenever something ends that involves people I really like, it's sad and I know I'm going to miss it. But you will get used to things being different. And you will still have one friend! Maybe you will still be able to e-mail with your buddy at his new job. He can send you morning e-mails, you can send him youtube links. And maybe you can still meet up for a drink every once in a while.
