So very sorry to read of your situation. I think perhaps your Mom may already know or at least have a feeling of what is going on. Perhaps that is why she decided to go on holiday with you at the last minute. It may not have been a conscious thing, but somewhere deep inside she knew she needed to be with her family. I am praying that she will not be in pain and that your family and she may spend her remaining days sharing your love. God Bless.
