Ditto the lifetime of good jobs.
If you were a good employee, and were let go due to the insecure ego of a manager, chances are they are hurting worse than you are. It is their loss and you opportunity for gain.
I was involuntarily transferred out of a great job at age 52 by an incompetent jerk. He had to hire three guys to do my job. Not one after the other, but three at the same time.
I was pissed at first but it never hurt my self image, because I was doing great work and everyone (except the new manager) knew it.
A couple years into the new assignment, I decided to take early retirement. As it turns out, getting pushed out by a bozo was one of the best things that ever happened to me.
Life is short. Don't spend it making a knucklehead look good.
Breathe, breathe in the air
Don't be afraid to care
Leave but don't leave me
Look around, choose your own ground
Long you live and high you fly
And smiles you'll give and tears you'll cry
And all you touch and all you see
Is all your life will ever be
