i can relate to that. my girlfriend is overseas right now but shes coming back home early this week, well anyways regarding the topic i myself am a loner
though i have alot of friends. but a loner can still get lonely sometimes so..
i deal with it by getting myself busy, you know watch a movie
read a book or something, browsing the internet or playing computer games, or make something with photoshop. XD even a phone call to a friend would help ^^
