It isn't doing anything for them. But it is sincere (I didn't say this in my post, but the idea is that my father actually did lose weeks of sleep over this). It, of course, should not be about you in this moment (this is hard to convey in a short post). But it seems far more supportive and honest than pretending that everything is okay and normal or acting like a robot.

Maybe it is also bad. I don't know. But the fake smile seems much worse.
