Congrats on sticking with your goal.
I think many of us are in a bind when it comes to having people we can count on should things go south. Even my pdoc and my PC doc are retiring in a couple of months. They are close friends, but they have each been there for me through lots of trials.
I am lucky to have a very dependable husband. Very lucky. He's very devoted. If he left or passed on, where would I be? I think about that a lot. We are both getting older. Rambling, sorry.
I hope your son comes through and meets your expectations soon.
Thinking of you.
