Moving on up (as in direction, not size)

After months of number crunching, we just signed a contract to list our house. It'll go on the market in 4 short weeks. Who knows what'll happen - we're listing it high to avoid a short sale, but come as close to breaking even as possible. I should be feeling stressed and... more stressed, but I'm feeling kind of sad. Our commutes are hell but the feeling of coming home every night to our neighbors, our park, our walk around the block, our adopted ferral cat, and even our tiny little home is going to be impossible to replace.
