I feel you, mine got lost/stolen about 6+ months ago, seemingly just inside my house, since I never take it anywhere. I’m not a hoarder, keep a relatively tidy house, though I have kids (so tidiness is only ever temporary). I turned over and looked through literally every room in the house, every cupboard, shelf, drawer, and piece of furniture was checked and re-checked and still, nothing. I only just got over it a few weeks ago and broke down and got another one, but this time got an AirTag for it. I’m just more annoyed at the not knowing part, hopefully it’ll just turn up in some stupidly ridiculous place that it hadn’t occurred for me to look, but I suspect I won’t see it again. I doubt it was stolen, since that’s seemingly the only thing gone. Potentially one of the kids broke it and, rather than tell me, they trashed it, but that doesn’t seem like them either or one of them would’ve broken ranks and confessed.

It drove me insane trying to find it before and it still bothers me, but at least I have a Steam Deck again.
