Woman to woman advice
Nice, long aromatic bath with candles. Turn the phone off. Give Mom a sleeping pill.
Go for a long drive, get out of town, have your nails done, see old friends, drink lots of wine.
Laugh at the situation, laugh at yourself. Breathe in the fresh air and relax. This place will still be here and none of us will have changed our opinions. Jump in when you feel refreshed and ready; by then it will be a breeze.
