A survivor of the 2018 Marjory Stoneman Douglas High School shooting took her own life last weekend.
According to CBS Miami, Sydney Aiello had been suffering from survivor’s guilt and post-traumatic stress disorder in the wake of the Feb. 14, 2018 shooting that left 14 students and three faculty members dead.
Aiello was 19 when she died, and her mother said she was struggling to attend college classes because she was afraid of being in a classroom after living through the shooting at her high school.
Ryan Petty, the father of one of the shooting victims, mourned the loss of Aiello.
"It breaks my heart that we've lost yet another student from Stoneman Douglas," Petty told CBS. "My advice to parents is to ask questions, don't wait."
According to the Miami Herald, Stoneman Douglas shooting victim Meadow Pollack was Aiello's best friend. Her friend Joaquin Oliver also died in the shooting.
Pollack's father Andrew, who has taken on a leadership role in helping to prevent school shootings after the Stoneman Douglas massacre, told the Herald he is devastated at Aiello's death.
"It's terrible what happened. Meadow and Sydney were friends for a long, long time," he said. "Killing yourself is not the answer.
"If anyone feels like that they have no one that can understand their pain, if there's any student out there that's having a hard time, please reach out to me on Twitter. I understand you. You aren't alone."
