God rest her soul, Snugs. How is your Dad doing with this?
As a grief counselor I can tell you (and you know this) .. your mind will be one place but your heart & soul another. the mind gets there first. Some times the heart & soul never do.. each person & their journey is different
When my favorite grandmother died some years ago, I found it would hit me in waves. I would be at work and found I needed a handkerchief handy to dab the tears. She meant so much to me, one of the two in my childhood whose love was unconditional, and even though I had not lived near her for 37 years, and knew she was with the Lord, happy to be with my grandfather again, I felt the loss of her so very keenly.
I'm glad you are getting on as well as you are. It must be a great comfort that her suffering is indeed over, and forever over, replaced by undiluted love and peace.
Prayers continue for you all.
