There's a hum to it. Low, constant, impossible to fully ignore. You're fine, technically. Nothing is wrong, exactly. But something isn't right either, and you can't quite name it, and the not-naming makes it louder.
That's not anxiety. That's not ingratitude. That's your actual life trying to get your attention while you're busy maintaining the one you settled into.
The restlessness is information. It's pointing at something. You already know what it is, you've been circling it for a while. These are for the moment when you're ready to stop circling.
