Anne says she heard the bomb went off and, as she is a trained first aider, she went straight to the town.
"I kept thinking to myself: 'Stay calm'."
We are now hearing a witness statement of Anne Cullen read to the inquiry.
She was working as a taxi driver working in Omagh went the bomb went off.
Helen adds that although the bomb "seems so long ago", to her "it is as if it happened recently".
She describes the months after the bombing as "very strange".
She says she was nervous and jumping at every noise.
She adds that she wasn't sleeping well and her daughter was having panic attacks and was "frightened by everything".
Helen says they got home and the enormity "began to sink in".
Their clothes were full of glass.
"We knew people were dead, but we didn't know there were so many."
Bodies were lying on the street, Helen says.
"The sights and sounds still remain with me today and I knew it was bad."
The noise from bomb was "tremendous but the screaming outside was much worse", Helen says in her statement.
"We made our way outside and were horrified by the sight of people running, screaming, looking for friends."
She says they were only in the coffee shop five minutes when the bomb went off.
She says the windows of the shop shattered and she was cut in the face by glass.
She says she didn't realise that the bomb was just outside.
Helen and her daughter had gone into Omagh on the day of the bomb to buy a school uniform for the new term.
When they reached the town centre police were moving people to the bottom of the street, away from the courthouse.
They decided to go to a coffee shop "until the scare was over".
Omagh was busy, Helen says in her statement there were "lots of cars parked on the street".
The inquiry has begun today's hearings and we are first hearing a written statement from Helen Kerr a survivor of the bombing.
Her statement begins that her daughter was "badly affected" by the bombing.
"She will not talk about it as she knows some of the young people who were killed."
She says they were lucky to escape without serious injuries but says it still has had an affect on their lives.
Good morning, and welcome back to BBC News NI's live coverage of the Omagh Bombing Inquiry.
The public inquiry was set up by the government to examine whether the 1998 explosion could have been prevented by the UK authorities.
This is the final week of this phase of the inquiry.
Twenty-nine people, including a woman expecting twins, were murdered in the Real IRA attack on 15 August 1998.
During the inquiry, we have heard commemorations of victims of the Omagh bombing as well as accounts from witnesses, first responders and people who were injured.
Today we are expected to hear from:
The inquiry is due to begin at 10:00 GMT.
That concludes the inquiry's hearings for today and our live coverage.
We'll start up again tomorrow morning when the inquiry resumes at 10:00 GMT. Join us then.

Rt Hon Turnbull comments to Mr Marshall that the events of that day have clearly "left an enduring mark on your professional career and private life".
He adds that Mr Marshall has recalled his account of events with a "commendable measure of sensitivity".
He says the people who planted the bomb could have told police where it was and "chose not to".
"They didn't give a damn about the consequences."
Mr Marshall acknowledges that the professional help has enabled him to cope better, and he urges those affected not to bottle it up.
He says "they desperately need" the help, and more importantly "they deserve it".
He says that part of the job was that "you would never admit to weakness".
But he says he has realised he can't cope like that and isn't ashamed to say he has been to numerous counsellors.
Mr Marshall and a number of his colleagues have been diagnosed with post traumatic stress disorder.
"The triggers are numerous, and they are constant," he says.
"They just jump up at you. You have really poor sleep, and I speak for a number of colleagues who were with me on that day."
"Alcohol abuse is very commonplace," he adds.
He says that it is not just the first responders, it also impacts the family and loved ones who "have to live it with you".
He describes the many months afterwards as an awful period of time.
He says the community looked to him as "the Omagh bomb man" and every time they saw him they ran.
On a number of occasions, a number of junior colleagues were at the "end of their tether," he adds.
He says that in hindsight he can understand why politicians and dignitaries made so many visits in the aftermath but at the time it had a "really negative impact on me to be continuously under that pressure".
Mr Marshall described the many hoax calls that followed the bombing as having an "horrendous" impact for many months afterwards.
He says it was like the hoaxer "knew our shift system" because most seemed to come when his section was on duty.
"They were just being retraumatised continuously."
