My Best Friend is moving to Korea?

She was supposed to move in July, but she is on the plane right now... i didn't even say goodbye. I am really depressed right now. Can you suggest some tips for me on how to calm down, and does anyone know how much shipping costs to Korea from Usa? Because i wanted to give her a present before she left, but since she's already on the plane right now.. i can't give it to her. Thanks in advanced. (: Trying to keep a smile on my face.
