I hear ya Heidi. My mom was on life support and our family was being encouraged to let her go. Lucky that we did not loose our faith as I will never forget the day my dad called me to let me know that she was off the ventilator,...it was truely a miracle I know in my heart.
It is very hard to watch our parents face health challenges and yet so important that we stay involved being their wellness advocate. Parenting our parents is not an easy job and probobly one of the hardest things one will face. It is in fact the worst part in my opinion of getting older.
Keep doing the things you are doing Heidi for your mom. It is very important as I am sure you know.
