Thank God I'm not the only one. I actually have friends, wonderful ones, but I don't see them much or even talk to them much. And it isn't like I'm supermom or anything, or even that my house is beyond passable (which it isn't). I only have 2, but my baby is still up a lot and I am just not back in the game yet.
I'll tell you one silly thing I've been doing to feel more connected--do you have a page on Facebook? I'll warn you, it's addictive, but I only spent a few days checking it obsessively before I mellowed into passive checking. But I've gotten in touch with college and high school friends, especially ones who don't live close, and it is a great way to know that other people are out there. Once you find your "friends," someone is online or has updated status or has sent an email pretty much all of the time--there's always something to do that makes me feel like I've been talking to someone. And you can do it whenever you want, obviously, so there isn't any scheduling or babysitting, and you don't need to be showered. :)
If nothing else, I can sure remind you that you aren't alone. We're all just trying to enjoy the days as they pass by, messy and exhausting as they may be.
Take care. :)
