We've had pain and trauma in our house over the years and for about a year, we seriously considered moving just because it was so painful to live here... but we stayed and I'm glad and the place is filling up again with good memories. We all take our pain with us wherever we go.
That would be the logical choice for this woman is to move if its too hard to live there. She will always see the corner where it happened, the house where the driver lived and so on.
