Severance agreement arrived, need a second opinion

I was offered 15 weeks of severance after 15 years as a dental hygienist, and I have a few days to sign. I am in Boston, in case local advice matters. It includes health coverage for a couple of months. What did you ask for?

Thanks for writing this out. I went through something close to it 10 months ago, and it settled down once I kept a simple log of every call and form.
