Do you ever feel like you just don't belong in your own home?

I moved out of my family's house about two years ago. Since then, I haven't really felt at home in my apartment. Like, all my stuff is there, I spend just about every night there, it's my registered mailing address, and everything, but it just doesn't feel like I live there. And when I visit the old house, I don't really feel like I belong there either.

When I was a kid, my dad was military, so we moved about every two years. I'm used to moving by now. But even in that short amount of time, each of those places felt like home to me. Now, I just struggle to feel comfortable anywhere. It's like I'm just a nomad waiting to move on to the next site. Or a person who is eternally crashing on someone else's couch, despite the fact that it's my couch and I pay the rent on the place.

Has anyone else ever experienced this? Is there anything I can do to cope with it? I just feel lost, and I need to get my bearings again.
