I have a very hard time with goodbyes. I never know what to say or how to act, and I'd rather just kind of nod my head and walk away. In fact, you might say that I'm not really in touch with my emotions, period, but goodbyes make me sad. I was doing some reading, and I saw an awesome goodbye that the apostle Paul wrote:

"Finally, brothers, rejoice. Aim for restoration, comfort one another, agree with one another, live in peace; and the God of love and peace will be with you." (2 Cor 13:11)

If you love someone, it's a great final greeting. If you are having troubles but have to say goodbye, it's a good reminder to end on a note of restoration. Perhaps my favorite thing, though, is the note on comfort, because giving people solace in trying times can be the most meaningful and vivid memory that they ever have.
