In 1999, I was once let go with 40 of my close friends. It felt surreal. Took me a long time to get over it.
Start economizing hard now. It won't hurt even if you get a new job quickly, and it may help a good bit down the road.
Put in for your unemployment. I never did because I was too proud, but now I know that was stupid. And remember that you'll have to pay taxes on your unemployment checks.
Finally, keep in mind that this is a low point. Things will get better. Trust me. They will get better.
Good luck!!!
