Lost my mum on 3rd Dec, after she had a heart attack and stroke on 27th Nov, completely out of the blue. She was 64.. I won't pretend to know how you feel, as grief affects us all uniquely, but I, like you, am at a loss as to how to figure out a way to function 'as normal' again and not think about her 24/7. Currently psyching myself up for her funeral, which is on Monday. Dreading it, still can't believe that it's even happening. Sending hugs. X
