Robin, I've just seen your post and want to offer my condolences and prayers, too.
We just lost my mother-in-law two weeks ago. I haven't posted anything here mostly because I've been involved with family and so haven't been on as much. My mother-in-law was a lot older than your Mom, but death is always tragic, in a way, because we are separated from the one we love.
AJ's comment above was really meaningful to me. We need to give ourselves time to grieve.
I will hold your heart in my heart and offer it in prayer.
Please take care, Robin.
