Awaiting a Possible Bad Day

I might be getting laid off from work in a few days. I've been laid off before, twice actually, but in those days it was just me. I didn't have anyone depending on me and I didn't have the kind of responsibilities that I have now. I gotta be honest with you I'm scared, the last time I got laid off was right before 9/11 so finding a new job was hard and I had to take a big pay cut to get the job I got. The economy now is almost as bad as it was then and before things get better I think it will be much worse. I'm not as young as I was then and my skill set is a lot more specialized now so I don't have as wide a group of options available to me.
