As I long ago learned, the support and love offered by your Cruisemates, is a truly sustaining force during times of trial simply because we all are so very sincere. You do indeed have a family here on which to lean in times of trial.
As has been amply pointed out, your memories will bring you comfort and as time passes, those fond memories will transcend much of the sadness and loss you now experience. Yes, the sense of loss will remain with you and that is good simply because such feelings will serve to trigger those marvelous memories.
God Bless you Jennifer and may you experience, "The Peace that passeth all understanding."
