Severance offer, what should I ask for? after 15 years as an event coordinator

The company sent a severance agreement with a release of claims, and I am unsure what to do. I do not usually post, so bear with me. 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 last year, and it got easier once I kept a simple log of every call and form.
