One of my first boundaries that was for ME was taking the phone off the hook at night.
Prior to this, I would lie there in the dark, waiting for it to ring with the news I KNEW was coming... my daughter was dead in a ditch somewhere.
The night I took it off the hook, I prayed and prayed first that God would be with my girl and keep her safe... then I took it off. I reasoned that even if she died, there was nothing I could do about it anyway.... so I took it off...
....... and slept like a rock!
It was wonderful.
