Just Fine Without You

A character leaves the usual setting, and is worried that things will fall apart without him or her around. When the character finds out that things are just fine, they feel useless and unneeded.

In fact, any number of crises have occurred, and a massive cover-up operation has taken place to keep the character from worrying about the home situation.
