Severance and unemployment, do they overlap? after 16 years as a medical assistant

I signed a severance agreement and I am worried about how to report it. I have read a lot of threads here and could not find my exact situation. I have a mortgage and need to plan. Who should I ask before signing?

Some states only count certain kinds of severance. A local workforce centre could tell me which.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
