Layoff happened 15 days ago, feeling lost - what worked for you?

They called a meeting on Thursday and 15 of us were let go. I had been there 15 years. It has been weighing on me all week. I have a box of my things and a short letter about benefits. Which steps were urgent?

Thanks for writing this out. I went through something close to it 13 months ago, and it settled down once I kept a simple log of every call and form.
