Mike, no matter how or when it happens, losing a parent forces you into at least a brief period of re-evaluation. I lost my Dad almost 43 years ago. Even though I was working and making quite decent money, pretty much doing adult things - and had been doing so for several years - there was always that hesitation, that moment of uncertainty... what do I do now?
It hit me like a ton of bricks in certain ways. For instance, I would never again be able to ask his advice. It was more complex in my case because only a few days earlier, we had discussed my mother's apparent slow descent into dementia, probably Alzheimer's (but I didn't request an autopsy to verify.) No matter what your age, no matter what you have been doing, your world changes. My friend, I wish you good luck in your adjustment to the new world that no longer has your father in it. Even when you know it is coming, it is a sobering experience when it actually happens.
