Condolences for the loss of your daughter. I too will pray. It will take a lot of strenth and I know that only God can give it to you. The wounds are very new at three years.
My son would of been 30 yesterday. It made me feel rather old. I still think of his favorite birthday dinner, swiss cheese, steak and blueberry muffins. We have a tradition, everyone can choose what they want for their birthday dinner.
Strength does come from prayer. Sometimes I forget, just the other day I was at wits end, then a feeling came over me. I sunk to my knees and prayed.
