The family of Sydney Aiello, who graduated from MSD High School last year, told CBS Miami that the teenager died over the weekend.
Her mother, Cara Aiello, told the outlet Sydney struggled with survivors guilt, had been diagnosed with post-traumatic stress disorder, and struggled to attend college classes over fears of being in a classroom.
Sydney was not in the Freshman Building on the day of the shooting, but was on campus. She was close friends with Meadow Pollack, one of the the students who was shot and killed in the shooting.
Tributes from people in the Parkland community were posted on Twitter following news of Sydney's death.
Ryan Petty, who's daughter Alaina died in the shooting, has launched an effort into suicide prevention since the shooting.
"It breaks my heart that we've lost yet another student from Stoneman Douglas," Petty told CBS Miami after hearing of Sydneys death. "My advice to parents is to ask questions, don't wait."
"Sydney spent 19 years writing her story as a beloved daughter, sister and friend to many," the page's description reads. "She lit up every room she entered. She filled her days cheerleading, doing yoga, and brightening up the days of others. Sydney aspired to work in the medical field helping others in need. On March 17th, 2019 Sydney became the guardian angel to many. It was a privilege to have you in our lives. Sydney, we will miss you and always love you. May you find peace in His arms."
