Your family has seen your worst angles. The fact they still set a plate for you says something.

Having been seen at your worst and included anyway is a specific kind of security. The people who watched you at fifteen, at your most difficult, have no illusions available, and they keep the place at the table regardless. That is not sentiment, it is a decision they renew without mentioning it.

Notice the plate, since it is the kind of thing that only becomes visible when it stops. Turn up to something ordinary rather than only to the occasions that require attendance. And where the table is complicated, the same holds for whoever does keep a place for you.
