Death is just as natural a part of life as birth, however there's nothing that feels natural about it. I often struggle with the thought that one day I may have to face a time as you are facing with my grandparents and parents, even siblings, and I pray to God I will never have to with a spouse or my children. It's the hardest thing I could ever imagine havin to cope with. You're going to need a lot of strength in the coming hours and days, so rely on those around you to find that strength.
Although prayers may not be a tangible thing that you can do anything with, know that there are hundreds, if not thousands of your fellow ODT brothers that are lifting you, your grandma and your family in prayers. If your grandma is anything like mine, she's probably reaching her hand out to her Comforter right now anticipating her arrival into paradise. If there's anythibg we can do, let us know.
