I'm sorry to hear that your daughter is in crisis. You know the drill....be there to support your daughter and her family, but keep in mind....she's got to go through the entire process. The husband will need support, but most importantly, your grandchildren are going to need more support than ever. Thank goodness they are not toddlers!
I do hope that you are taking care of yourself. I'm keeping you and your family in my thoughts and prayers.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
