I'm very sorry to hear of your loss. There is comfort that can be found at Revelation 21:3,4, which says, "And he will wipe out every tear from their eyes, and death will be no more, neither will mourning nor outcry nor pain be anymore. The former things have passed away." Soon, losses we sustain of any kind, be it the loss of a loved one or our peace of mind, will be done away with and reversed as if they never happened at all. I hope this promise can carry you through this difficult time and beyond.
