I know how this feels Volunteer, I was laid off after 20 years, not that I didn't see it coming.
In my State you can file for unemployment (and should immediately), but would receive no compensation before the 5 months that you are still receiving a paycheck; vacation pay is also a consideration.
You would have to report earnings during that time, but after the five months (+ 3 weeks, I think), if you are still unemployed, you would begin receiving benefits. If you don't file immediately however, it may reduce your benefits.
Because I am in Texas, it never took me more than a month to become employed, I wish you the same luck.
God bless you. Thank you!
