How to cope with the loneliness after a party?

Wow, I've actually never known or heard of anyone else who's experienced this kind of thing...usually people get tired at some point and *want* the party to end. Or as other people start leaving, the party just naturally winds down and it's easier for you to go since there's nothing to do.

I think post-party depression (har) might be a sign of a much deeper problem...you need to live your own life instead of letting it revolve around the time you spend with your friends. Learn how to enjoy yourself without the help of other people. Also remember that even away from a party, it's possible to interact with your friends. You can talk to them at school/work, or if you're at home you can send them an IM, post on their Facebook/MySpace, call 'em up or fire up Skype, play an online game and trashtalk them over voicechat...there are plenty of ways to be social without the alcohol.

Jam it back in, in the dark.
