Time heals all wounds. So they say. I don't know that wounds such as your loss is ever really healed. But I do know that, with time, the pain will not be as sharp and keen as you feel now. I also know, from my experience, that Jean is still with you and her family.
Every time you think of her, or talk and remember times shared with her, she will be there. I believe that no person is ever truly dead and gone until there is no one left to remember them and speak their name.
From my faith to you, may the peace and love of Jesus Christ be with you now and forever.
