Grieve. I know noone's died, but it's a huge loss, and I think it's appropriate to grieve.

And then find some things you love to do (photography, painting, walking in the sunshine, etc) and think of all the things you normally have no time for, when you're at work, and DO some of them!

And then sit down with your budget, and figure out an ETA for when you need to go back to work. And then give yourself some guideline for when you'll take the job hunting up a notch.

And be really, really gentle with yourself, my sweet.
