From personal experience (laid off from long time job at the beginning of 2003 until finding a temp job or two in late 2004 and 2005), I know how debilitating it can be to your self esteem. Especially when your spouse is in full hate mode towards you as mine was then!
Great that you took the initiative to celebrate her success and that she reciprocated. I'm sorry for her that the company can't process her paperwork immediately and she will be very anxious until then - so please keep that in mind.
From a practical standpoint, I would suggest that W keep her resume updated (unfortunately you never know when you have to pull that out) and to network once the initial euphoria rush has abated.
Also - cool that both of you enjoy sushi. My D likes to make it on occasion but without any seafood. I heard that at our State Fair someone was peddling Deep Fried Sushi - just like they deep fry everything else. That is just pure wrong!!
