Death is hard especially when an unexpected tragedy happens like 9/11 and the many tragedies since then. The numerous school shooting we hear about on the news along with how many drunk drivers have killed innocent children with their family members. There is nothing we as humans can say to ease the pain of the death of a loved one, but Jesus can. Run to him when your heart is breaking and let him hold you through the pains of this world. He is the only one who can help you. God loves you so much. Death isn't a punishement for believers, but a reward to escape the further pains in life and live with Jesus in heaven.
Keep believing and never surrender to this world. Your loved one deserves the best and so do you. Keep looking up and know that you will unite with your loved one one day.
