Working in the tech industry, I've been laid off a few times over the years. After the second time, I stopped worrying. Because somehow, I do manage to get another job. So my suggestion to anyone that lost their job is to take a week off to relax and regroup. When you're relaxed and ready to go, set up a daily schedule for yourself.
Spend an hour or two each day searching/applying for jobs.
Spend the rest of your day improving yourself. Take some courses at your local community college, learn some new skills or refresh your existing skills. Or volunteer your time for a charitable cause. Or get some stuff done around the house.
Also, get in touch with family/friends you haven't seen in a while. Catch up over lunch/dinner. Staying at home all day really sucks the motivation out. You need to interact with people and socialize. Helps keep your mind off the fact that you're not working. Also, your family/friends might have leads for job opportunities through people they know.
And consider taking a mini vacation. With laptops and cell phones and other forms of technology, you don't have to be stuck at home searching/applying for jobs. You can do it at the beach as long as you have wifi or mobile broadband.
