Numb isn't nothing.
It's usually what happens when something has been too much for too long — the volume gets turned down on everything, including the good parts. It's not coldness and it's not a character flaw.
So no reassurance here. Just orientation: where you are, what's around you, small choices that are still yours.
Where you are
What's the temperature of the air on your hands? Not good or bad. Just warm, cool, or neither.
"I don't know" and "I can't tell" are complete answers.
One tiny choice
Not because it matters. Because choosing is a thing you can still do.
Either one. There's no right answer.
