You only have one Mother and you are never ready to say good bye. I don't care how long they have lived.....
But, it sounds like your Mom was the lucky one to have such a caring son such as yourself.
She is resting now and she is at peace.
My Mother-in-law passed away unexpectantly September 30th. She was everyone's rock and we loved her so much. During Christmas, we kept noticing power surges in the house. My Father-in-law came out of his bedroom and said the electricity kept trying to go off in his room......My sister-in-law was sitting in the living room and the lamp behind her starting flickering. She thought something was wrong with the wiring and I told her there was nothing wrong with the wiring. It was just Mimi letting us know she was there. Have there been any power surges since then? No.
So, watch for signs because she will ALWAYS be with you.
