Phyllis, so sorry for your loss. I hope you can find comfort that she is at peace. For me, a death during the Easter season is a significant time. We lost my husband's grandmother seven years ago, on Good Friday, she was a devoted Catholic. Today is Holy Thursday, and your sister going home to our lord reminds us of his suffering he endured for us. Good Friday, our lord was at rest, your dear sister is now at rest. She will rise again as our lord has promised, and we will all be together with our loved ones one day.
I hope that you can find peace in your memories of your sister, find hope in the Easter season, and comfort that many of us here join in your sorrow.
