I am sorry for your loss. Losing a friend or family member in death is never easy. One thing that helps me cope with the loss of a loved one is a scripture at John 5:28, 29. It states, "Do not marvel at this, because the hour is coming in which all those in the memorial tombs will hear his voice and come out, those who did good things to a resurrection of life..." Soon you will be able to see Rev. Hartkopf again because our creator promises to resurrect those sleeping in death. I hope that this promise from the Almighty God has offered some comfort.
