I have to say that PC is a pretty awesome place. There are really great people here that can help to fill a void in your life. I wouldn't rule out trying something new again though. It's something I need to work on myself.
Maybe try volunteering? A part time job? Join a gym? An online blog (anonymous of course)? Take a college class?
Just throwing out ideas. I'm trying to find something for myself now too. I'm officially an "empty-nester" now and trying to find things to do also.
