(WFOR/CNN/Meredith) -- The Marjory Stoneman Douglas (MSD) High School community in south Florida is mourning another loss.
Sydney Aiello, 19, was a recent MSD graduate who was at the school the day of the mass shooting when 17 people lost their lives.
Aiello's mother said her daughter took her own life March 17, just more than a year after the deadly Feb. 14, 2018 school shooting.
Aiello was close friends with Parkland shooting victim Meadow Pollack.
Aiello's mother said that her daughter felt survivor's guilt and was diagnosed with post-traumatic stress disorder (PTSD) after being on campus the day of the shooting last year.
Aiello's mom said her daughter struggled to attend college classes because she was afraid of being in a classroom, and that she was sad but never asked for help before she killed herself.
Her mom hopes Sydney’s story can help save others.
Ryan Petty’s daughter Alaina died in the shooting. He said it breaks his heart that the community has now lost another MSD student.
He's focused a lot of effort on suicide prevention since the Parkland tragedy, worried that traumatized students might take their own lives.
Cindy Aronberg Seltzer is the president and CEO of the Children's Services Council of Broward County.
She said there are many community resources like the 211 hotline and a new program called Eagles' Haven, opening next month in Coral Springs.
Seltzer said the Parkland tragedy proved that we all need to work to get over the stigma associated with mental health problems and the inability to ask for help when we're struggling.
She said it's important for parents to look for suicide warning signs like kids who hurt themselves or stop taking part in important activities.
"Parents have to be a little more aggressive when they see those signs and not just wait for the child to ask for help but maybe to take them to those resources,” Seltzer said.
Aiello loved yoga, and her mom said she wanted to dedicate her life toward helping others.
Now, you can help her family by donating money to a GoFundMe account set up in her memory to help pay for funeral expenses.
The GoFundMe page reads:
Sydney Aiello was born on January 27th, 2000.

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.
