Just wanted to let you know this is also something I struggle with and am currently trying to overcome. Part of my problem at this point is that I'm in a new area (we moved a little over a year ago), so I'm struggling to find things to do and people to do them with... Add to that the homesickness for where we used to live, and it's an uphill battle for me.
I don't have any advice, but I'll be rooting for all of us on this thread!
