It's an odd concept "getting there " isn't it? After all our lives cannot be the same after a bereavement as they were before. Someone very important is missing.
Obviously, there is a difference between the first raw grief where the very air hurts your skin and you cannot stop crying and the sadness you experience three years or whenever after a death, when you think of the loved one, and actually manage to laugh at the memory, or at least not burst into tears.
I would be sorely tempted to tell anyone who felt I should have got over someone's death, that they could take a running jump at themselves.
Yes, life goes on, and yes, we cope. We even manage to be happy again, but we go on missing the dear departed whether they are our children, spouse, parents or brothers and sisters.
