I've heard some say that losing a job can be as hard as experiencing a death in the family, psychologically. For some of us going to work may be our home away from home. Perhaps it's the only workplace you've known. Regardless of the situation, it's never easy.
I've been through a few downturns, and rounds of layoffs, on both sides of the table. There was a time I hit rock bottom after losing a job and someone I barely knew spoke some words I'll never forget...
"It's just a job."
You're not defined by what you do with your life from 9-5. Jobs come and go. Life goes on.
