How to get over her and this rut?

I really liked this girl for about a year. Unfortunately for me, she is moving to a different country tomorrow. Unfortunately I didn't make a move until i found out that she was set on moving and it was too late. This blows, since she explicitly said that we would be dating if she didn't have to move. There was also a joke about an anchor baby some where in that conversation lol. I'll definitely miss her but what really bothers me is missing the little things. Like every time I'm gonna drive in the direction of her place, i will remember of how I used to pick her up. Every time I watch certain shows on TV, I will remember watching them with her. After she leaves, I probably will never see her again since she is moving to Kazakhstan (save the Borat jokes lol). How can I get over these feelings? Everything just feels so gray. I've gone through break ups before but this one feels so much worse. I got one last chance to see her tomorrow night at the airport and that's it. Still don't know what to say...
