Just Came Back From First Visit. How Do We Deal With Being Apart Again?

Me (M 19) and my girlfriend (F 17) just finished having our first visit in the 7 months we've been dating. It was amazing in every way and it was most definitely the happiest week we've both experienced in a very long time.

The problem is, now that I am back home, we are both finding it incredibly hard to deal with the parting grief. She says she hasn't been this upset in a long time and I would have to agree with this statement. Is there anything that you guys/girls have done to ease the pain? If you have any suggestions it'd be much appreciated!
