Should I negotiate my severance? after 10 years as a store manager

I was offered 10 weeks of severance after 10 years as a store manager, and I have a few days to sign. It has been weighing on me all week. There is a non-disparagement clause. What did you ask for?

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.
