Layoff happened 14 days ago, feeling lost - 12 weeks in

They called a meeting on Wednesday and 14 of us were let go. I had been there 14 years. I have a few weeks of savings and a rent payment due. Is there a checklist I should follow?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
