Ms Travis told the inquiry that not a day has passed since then when she is not in pain and said she would never forgive those responsible for leaving the bomb in the Co Tyrone town.
Ms Travis said her mother had suggested the two of them leave the area to go to the Dunnes shop, but she had said they should stay.
She said: “I said ‘I was sorry, we should have gone to Dunnes when you said’.
Ms Travis said her face was covered in rubble and she could not see properly due to blood from a cut on her head.
Ms Travis said she finally saw her mother in the middle of the road.
