Dedicate a work space and stay far away from it, when you're not working. Maybe get a large whiteboard to hide it from your field of vision when not working (bonus: whiteboard!). Separating work from personal is the most critical part of being able to work from home without always being "at work." I'm lucky enough to have been remote for years, so COVID hasn't changed my pattern but I know the pattern can be hard.
Also, wear pants. They don't have robe fancy but don't sit around in your pajamas because then you're never really "at work" and you'll never stop being somewhere in the middle.
The people who suggest taking a walk are spot on too. You have a rather small space for being remote. Having a "going to work" routine helps you mentally prepare and the reverse does... well... the reverse. If you like beer/wine/pot/games/etc, getting your favorite at-home vice/hobby going after work is another good mental signal.

Good luck! Stay safe (mentally and physically)!
