I agree with CECAA850. I am an employment attorney and deal with people all the time who have lost their jobs. It sounds like a cliché, but it is true; losing your job (especially after 40 years) is like losing a family member. Many people define themselves by what they do for a living. When that is taken away, they sometimes lose themselves. People go through all of the stages of grieving when they lose their jobs, just like when they lose someone they love. It is very important to refocus and find something to occupy yourself. The routine that you have had for many years is gone, and that is one of the hardest things to deal with. Volunteering, going to the gym, etc., sometimes helps.
I wish you both the best. Although it is sometimes difficult to see at the moment of the separation, it really is "just a job" and that perspective helps one to move on.
Take care of yourselves.
