Severance offer, what should I ask for? - what worked for you?

I was offered 5 weeks of severance after 5 years as a delivery driver, and I have a few days to sign. It has been weighing on me all week. It includes health coverage for a couple of months. Should I see a lawyer?

Thanks for writing this out. I went through something close to it 2 months ago, and it settled down once I kept a simple log of every call and form.
