Crack, go read my latest blog post on making friends:

I felt pretty friendless not so long ago. Almost all of my friends had moved out of town. I'm thankful that those friends are the kind of friends I can call up or see every few months and it feels just like yesterday, but I wanted friends in town. Through playing rec sports and going to parties hosted by people I had only met once, I made friends. There is definitely a certain amount of emotional risk in attempting to make friends, and it can be hard, especially for adults. But you can do it. It's not so much about being the friend you want to be, but just getting out there--it's like trying to find a date, to be honest. You aren't going to find friends by staying home. Volunteering, playing rec sports, going to events in my community--all of these things brought me into contact with people I now consider friends.
And yes, we all need friends--the key is to make them before you REALLY need them.
