I'm so sorry to hear your news.
Just three days ago we posted in the same thread about our Mums nearing the end.
My Mum passed away this morning too,at almost the same time as yours did.
Like you,I have plenty to do,but I've never lost anyone so close and it's a unique sorrow.
The only comfort is that Mum was sleeping comfortably and never woke up.
I wish you comfort and strength in the coming days. Anne X
