Going days without eating has likely put you into something called nutritional ketosis. That's perfectly normal, and has nothing to do with diabetes. Some type 2 diabetics were or seemed asymptomatic at diagnosis, but from the sound of it, you're fine, diabetes-wise. If you're worried about ketones that aren't connected to perfectly healthy nutritional ketosis, well, those are usually linked to T1, and you'd almost certainly get symptoms then. Especially the thirst and weeing. We can't diagnose on here, but odds are you're fine.
That said, if anxiety is getting to you, get the tests done. Peace of mind is more than worth it, especially in a year that has everyone running on empty.
