Severance and unemployment, do they overlap? - 7 months and counting

I was offered severance of 6 weeks after being let go as a school bus driver and I am unsure how it affects benefits. It has been weighing on me all week. The agreement mentions a release and a payment schedule. Who should I ask before signing?

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

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