I'm so sorry for your loss. A comforting thought I found in the Bible:
found at St John, chapter 5 and verses 28,29; KJ "Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, and come out..." This hope of a resurrection has brought me great comfort. I hope it does the same for you. May you find peace.

Our condolences on the loss of your mother, our thoughts and prayers are with you. May you find comfort in knowing she is in a better place.
