The fear and desperation that grip you after you've been laid off are destructive emotions. They distract you from doing the work you need to do . That's why you can't let those emotions consume you, says Dr. Richard Bayer, a former professor of economics and ethics who currently serves as COO of , a career coaching and outplacement network.

"Resist the urge to think of unemployment as the end of the world, no matter how upsetting it may be," he says. "Think of it instead as an opportunity to improve yourself and to make a fresh start. Maybe you're going to find out that what you enjoy doing and do well is different from what you were doing. You can end up better off than you were before."

The key, says , is maintaining a positive attitude because potential employers can detect a candidate's desperation as easily as a shark can smell blood, and they don't like it. To keep a stiff upper lip, Bayer offers the following seven tips for thriving after a layoff, even in a bad economy.

1. Negotiate for the best possible severance package.

Don't think that you have to accept whatever your manager or HR puts in front of you as is, says Bayer. Your severance package is negotiable, he says, so don't feel pressured to immediately sign on the dotted line. Take the time to read the severance package, even if it's 20 pages long.
