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. I have read a lot of threads here and could not find my exact situation. I want a plan before I speak. Did it get easier afterwards?

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.

Do not wait until a bill surprises them. The longer it goes, the harder it gets.
