How do I tell my family about the layoff? after 17 years as an accounts payable clerk

I was laid off 18 weeks ago and have not told my family because I do not want them to worry. There are 17 people counting on me, so I am trying to be careful. I want a plan before I speak. How did you handle it?

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