Dear Lotusangel, my heart breaks for the loss of your dear son. May the love of your granddaughter and friends help you through this most difficult time. This is something parents here fear all the time. Praying for God to bring you comfort and peace. We lost my nephew a few years ago and his mother has found great help with the group Compassionate Friends. You might see if they have one local. The sadness doesn't lessen but it will get softer....in time. Hugs.
