Unemployed for the first time

I am 46 years old and have been someones employee for 24 years. Now don't get me wrong I am also a mother, wife, daughter and sister. That is how I see myself, unfortunately as you can see work came first.
That is until Monday ( June 29th, 2015).
I joke that I did not choose my midlife crisis, rather is found me. The company I have been with for half my life is going through major changers and stress. With impending possibilities of the company closing it was time to reevaluate my life and priorities.
I did a lot of sole searching over the course of a year. Was I up to the challenges of starting anew with the company? How will this effect my family? My stress? My anxiety? After a lot of sole searching and planning and evaluating I knew I needed to give notice. I planned and saved to allow myself a few weeks to spend the summer with my children and figure out - now what?
