Losing a job is a very traumatic experience. I quit a job awhile back that I really did like, I'd been there a long time but there were some things that happened and other things that were going to continue to happen that caused me to finally leave. I was devestated because I didn't have another job and I was really suffering the loss of something I cared about.
I know - it sounds reckless to quit a job without another lined up, but I saw the situation coming to a head and started planning about a year in advance (and this was just before the economy took a header).
I went into a depression (and I have never even been closed to depressed before) and I slept a great deal. I DID get up every morning and made a job out of finding a job and sent out resumes buy the dozenes. I networked, I created a great resume, I cleaned the house and I did all I could to keep my mind off my situation. But, when I
wasn't able to keep my mind off of it, I suffered. I slept a lot, I cried, I felt useless and most of all I was terrified (what if I could never find another job that I loved??).
Talking to others in the same situation helps, as does therapy and/or career counseling.
Just when I started to feel better, I got a job.

The whole ordeal lasted 3 weeks, but it seemed an enternity.
The whole point I'm trying to make is that it's a tough transition and, when you're used to being valued as an employee and a teammember, sometimes the household chores remind you of how "unimportant" you are now that you're unemployed (I know that isn't TRUE, but it's how your mind works when you're in this situation). A huge suggestion I have is that when you're unemployed, it's a GREAT time to do self-assesment of your career skills, what you have done right and wrong in the past and what you might want to do in the future. Read books, take classes, research.
It helps to remind you that you are still developing yourself, even when you're not on the job. And then when you do find a new position, what you've learned and discovered about yourself will be very helplful.
