Severance agreement arrived, need a second opinion, bookkeeper here

I was offered 6 weeks of severance after 6 years as a bookkeeper, and I have a few days to sign. It has been weighing on me all week. I do not want to leave money on the table. Should I see a lawyer?

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.
