Sybil Ramsaren says she can't stop reliving September 11th, 18 years later.
"It was just terrible," she said. "It was just like yesterday."
Every year, Ramsaren comes to the memorial to honor her daughter, Sarah Khan, who died at the World Trade Center at the age of just 32.
Although the city and country have largely moved on from the 9/11 attacks, some of the people whose loved ones were killed say they feel stuck in time.
Hiram Gonzalez lost his sister, Nereida De Jesus, who was working on the 98th floor of the South Tower that day.
"Every time this day comes by, it's unexplainable, the feeling of how much I miss her," Gonzalez said, fighting back tears. "I never had the chance to hug or talk to her."
Claudia Szurkowski never even got the chance to meet her father, Norbert. He died eight months before she was born.
"He actually picked my name for me, so that's why it makes me really happy," Claudia said. "All of my family tells me I look exactly like him, so it gives me that sort of relief."
The attack forced people like Claudia to experience loss and grief from a young age. John Terry was eight when his aunt, Lisa Marie Terry, died.
"My life went, very quickly, from the kind of a carefree, everything is whimsical, to just very, very quickly realizing the world is not 'Barney,'" John Terry said.
That feeling has not changed as the aftereffects of 9/11 continue to take a toll on the city and country. Bridget Gormley's firefighter father survived 9/11, but he died 16 years later from bladder cancer, one of the diseases linked to the toxic debris and dust he inhaled when he responded to the attack.
"What a lot of people don't realize outside of New York is that this is an issue that a lot of people have to face every day," Bridget said. "The echoes of the effects are still happening today."
The families of the victims killed on that day, and in the aftermath, are now linked forever in a tragedy that continues to unfold.
"How can you ever forget? Never," Ramsaren said.
