How do you reorient yourself once you wake? That can be hard and I find myself feeling anxious when it happens TBH.
For a long time, I would wake up with a start wondering where (and even when) I was. I would struggle to remember which country I was in and where I had gone to sleep. Having something significant nearby really helps. For me, it's my dog. When I wake and he is at my feet I know I am in Canada and safe. You'll need to find something that can cue you to where you are.
