Layoff happened 15 days ago, feeling lost (Baltimore)

I was let go as a customer-service rep this week and I am still in shock. I do not usually post, so bear with me. 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 settled down once I kept a simple log of every call and form.
