I am so very sorry for your loss. May you and your family find comfort in the days ahead from the many memories that you created and shared w/him over the years. He is at peace now, no more pain and is always there within your hearts.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
