Hiding a layoff from the family, bad idea? (update)

I have been leaving the house at the same time each day so my kids do not notice. Bills are coming up and I cannot keep this quiet. Did it get easier afterwards?

Kids often pick up more than you think. A short, calm explanation helped mine feel secure.

Shame is common after a layoff even when it is not your fault. Saying it out loud to one person first helped me.
