Good Morning Zircon,
Because of my XAH's military career I moved plenty of times. Sometimes the places were great and sometimes not, but there was always an adjustment period, especially when downsizing, or downgrading. They never felt like home right away, but they always did after a while, and there was always something about each place that I missed when the next move came.
The quicker you can get things organized and decorated, and get some friends over, the quicker you'll get over this wonky feeling. It may take a while, but it will happen eventually.
