The terrible things that happen to us in life never make any sense when we're in the middle of them, floundering, no end in sight. There is no rope to hang on to, it seems. Mothers can soothe children during those times, through their reassurance. No one worries about you like your mother, and when she is gone, the world seems unsafe, things that happen unwieldy. You cannot turn to her anymore, and it changes your life forever. There is no one on earth who knew you from the day you were born; who knew why you cried, or when you'd had enough food; who knew exactly what to say when you were hurting; and who encouraged you to grow a good heart. When that layer goes, whatever is left of your childgood goes with her. Memories are very different and cannot soothe you the same way her touch did.
