Hiding a layoff from the family, bad idea? - any advice?

I have been leaving the house at the same time each day so my kids do not notice. There are 13 people counting on me, so I am trying to be careful. Bills are coming up and I cannot keep this quiet. What did you say?

I told my partner the same evening with a simple plan: what happened, what I was doing and what I needed. It was a relief.
