My best advice is not to panic and do anything that's a major change right now.
I was laid off in May, 2009 from a position I'd had almost exactly 4 years. The company all of a sudden decided that they were going to restructure the sales department, and 200 of us (40%) were gone by the end of the following week. There were "business rules", but the scarlet letter remains.
My first piece of advice: don't take your kids completely out of day care unless you know you're going to remain a SAHM. We moved ours from full-time to part-time. They were 1 and 3 at the time, and I couldn't focus on getting a new job with their needs. Also, taking them out and putting them back in was going to be a nightmare. What if their spot was taken? What if they didn't transition back in well? So, we decided on MWF to allow me the opportunity to interview and job search.
I was one of the fortunate who got back to work quickly. I was laid off 12 weeks total, but I knew I wasn't going to match my salary in an industry (pharmaceuticals) that's literally imploding on itself. I'm still in the industry, I took a corporate position with a small company at 80% of my salary, 0% of my flexibility, and no bonuses. It's been a hard transition.
I still wear the scarlet letter of being laid off. I really had stopped loving my company once they turned on their own values, but getting past why you were let go and people who didn't work as hard or take the job as seriously remained is really tough. Most of it was geographic location, but managers had input as well. Not well done.
Let people know! Start networking. You never know who may be able to help you get into an organization that will be the start of your new career. I had NO problem opening my big mouth to see if people were willing to help. I never asked outright but gladly accepted offers.
Good luck. Feel free to connect with me privately if it helps to have someone to relate to the issue. My emotions were suppressed until about 7 months later when I finally let them out, and I'm still dealing with them. Other people I know decided to take trips, buy nice cars, etc. I just wanted to get back to work as it had been a HUGE part of my life.
Also, deal with it however you need to. No one can tell you how to feel or how to deal with it. We can just make suggestions, and hopefully, your friends treat you no differently - even if you have to cut back on certain things.
