well i feel a similar way when my DH goes away for the whole weekend but its more to do with having a 2 year old that i have to look after the whole weekend by myself. its fine during the week but i really look forward to the weekend when he is here to help out as well. just have to try and snap yourself out of it! :-) maybe if you go to your friends place, the the movies or do something special yourself the time will go by faster.
