1.) Take one day. When it feels like your world is ending it can be tough to think about anything else, so do what you need to do to clear your mind. However, you need to put a time limit on your groveling or you could end up wallowing forever. If that means sleeping in bed for an entire day, do it. Maybe it means going for a run or watching your favorite movie on repeat. Whatever it is that you need to do, take a day to completely absorb yourself in whatever situation you’re in, then wake up tomorrow, and begin to move on.
2.) Comprehend your new reality. Constantly saying “If only this hadn’t happened…” to yourself won’t get you anywhere. This did happen. If you lost your job, you need to stop and look at your current situation without your mind getting carried away. So sit down and take a look at your finances. What are your necessities and what will it take to pay for them (and no, cable television is not a “necessity”)? Exactly how much money do you need to make to keep a roof over your head and food in your belly?
3.) Make a plan, in writing. And don’t generalize. Saying, “I’ll find another job,” isn’t going to help you right now. Of course you will, but how? Writing down a serious of steps leading to a job would be much more constructive. Something like: 1.) Talk to everyone I know to see if they know if their current job is hiring, 2.) Search the want ads, 3.) Update my resume, 4.) Go down to the job center to check current openings, etc.
4.) Find the reason (if there is one) and learn from it. Sometimes things happen for no reason, and there really is no lesson involved. Some things, however, do have a reason for occurring. Is there a reason you were laid off instead of your coworker? It may be that you were simply at the company for less time. Finding the reason allows you to either prevent this situation from happening again or absolve yourself from feeling guilty over something you had no control over in the first place.
5.) Appreciate the things you do have. No matter what, you still have some things to be grateful for. A divorce is rough, of course, but you still have you children, right? Try to focus on other aspects of your life that are going well. Maybe this whole situation has made you realize that you have some seriously amazing friends who would do anything for you.
