PT,
Had to go back and re-read things. MIL just had heart bypass not too long ago. You folks have had your hands full, for sure. In our toughtest times, I'm reminded of "footprints in the sand" where He doesn't abandon us when there are only one set in the sand of our journey's steps, but He's carrying us.
Prayers for strength, His GRace, mercy and peace for all involved.
Keep the Son in your eyes!
