It's devastating to lose a loved and I'm so very sorry for your loss. It leaves us wondering why but Romans 5:12 gives the answer. Hope is found at Isaiah 25:8 which says that God will swallow up death forever and wipe away the tears from all faces. He will resurrect many to live again on a restored paradise earth as recorded at Acts 24:15 and Psalms 37:9-11,29 May you find comfort, jw.org
