I am joining this conversation late, and want to offer some fairly radical advice.
I get the impression that you are taking care of everyone except yourself, and that your health is in trouble. You need a year off.
Sell everything: the house, your practice if you own it, ditch the luxury cars. Rent in a community where you can afford a comfortable apartment or nice home where the schools are decent for your kids. During your year off, get to know your family and spouse again.
As others have pointed out, our nation is entering a crisis, and having your funds in very conservative investments would be a good thing.
Do some travelling, read those books you have always wanted to read, and then comes the scary part. You are going to find out how people really feel about you. Are you just a wallet for those around you or are they really there for you?
When the year is over you will be a different person and you can decide if you want to go back to medicine.
For the record, I had cancer seven years ago and went through a kind of forced year off, and the changes and benefits have been radical.
