Layoff happened 14 days ago, feeling lost - what worked for you?

I was let go as a marketing coordinator this week and I am still in shock. Thank you in advance. 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 5 months ago, and it settled down once I kept a simple log of every call and form.
