Severance and unemployment, do they overlap?

I signed a severance agreement and I am worried about how to report it. It has been a long 16 weeks. I have a mortgage and need to plan. Who should I ask before signing?

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.

Before signing, I asked a friend who is a lawyer to look at the agreement. It was a short conversation and worth it.
