I'm sorry to hear this has been a trying month. Being laid off is bad enough without having to worry about your children. I'm sure things will work out in the end: the universe has its way of making things balance out. However, the universe likes to take its own sweet time. I often find myself muttering, "Balance NOW, dammit!!"
On the job hunt front, I find that nepotism, networking, and the classified ads work best (in that order

). I got little to no response from online sources. My staffing firms were nice, but had a hard time finding me permanent work.
In the end, I found a great job through the classified ads. As a matter of fact, it isn't even the job I applied for. It worked out for me, and I'm certain it will for you.
