The video shows Cassidy Slater, of Scranton, holding up sheets of paper describing the hardship she faces at her elementary school every day from bullies.
"There's 4 of them and only 1 of me," she wrote on one paper.
Cassidy said the bullies would spit on her, kick her, pull her hair, and threaten her at John Adams Elementary. Another time, they spilled milk on her jacket, she said.
The feedback she has received from the video is nothing short of incredible.
"It’s overwhelming," Cassidy’s father, James Warner, told InsideEdition.com. "Words can’t even begin to describe the gratitude towards everyone that’s reached out to her."
Among the video's many viewers were the New York Yankees. Some members of the team responded to her with a video of their own, using the same format with pieces of paper.
The video started with Yankees pitcher CC Sabathia holding up a piece of paper that says, ‘Dear Cassidy, My name is CC Sabathia and I play baseball for the New York Yankees." The next sheet read, "My teammates and I wanted you to know that we care about you."
Hey Cassidy - we saw the video you made and from all of us here at the New York Yankees, we want you to know that you are not alone. We have your back! https://t.co/uuRb0ghzf1 pic.twitter.com/V2EeuJ1YmW— New York Yankees (@Yankees) April 18, 2018
The camera then cuts to some of Sabathia's teammates, each holding up their own signs.
"We got your back," read a handful of the cards by multiple players in English and Spanish.
But perhaps the most thrilling note came from center fielder Aaron Hicks. It read, "You can sit next to us at lunch anytime. In fact, we have a seat for you at our lunch table in the clubhouse."
When she saw the Yankees' response, Cassidy, a fan of the team, was ecstatic.
"We showed her the video last night after school and she was just thrilled," Warner said. "It was amazing to see the look on her face when she saw the video."
The team has invited Cassidy to a home game in the Bronx the week of June 11, during which she will be honored.
"I think that meant a lot to her because they went with her idea," Warner said. "What really got her excited is when they invited her out."
The original video Cassidy posted on her own Facebook was later deleted because of her age. The legal age to have an account is 13.
But her mother, Jen Slater, has re-posted the video to spread awareness once more.
Since re-posting the video, it has been shared more than 260,000 times and is making its way across to world and to several movie stars.
Hugh Jackman re-posted Cassidy’s video saying, "I want you to know you’re loved, special & smart. You’re strong, funny & beautiful both inside and out. BULLYING IS NOT OK."
“It’s reached people that I, never in a million years, thought that it was ever going to reach from the everyday person over in Australia to famous movie stars to famous athletes,” Warner said.
Warner said her life at school has changed since the video was posted, with children giving Cassidy hugs and telling her they are her friends.
The bullies have not said anything, but the school has rearranged Cassidy’s schedule and has put safety plans into effect.
Her dad also said a lunch lady who was supervising the children during the bullying went onto social media and trash-talked Cassidy. Warner went to the school on Monday to tell them his daughter was now being bullied by staff and the employee was removed from the school.
Warner says the reaction to the video is bittersweet.
"When I think about it and talk about it, I get choked up," he said. "I feel so bad for my daughter, but then again the amount of outreach and support from everybody, I’m so thrilled and happy for her."
He says he is grateful for the positive thoughts because it brightens up Cassidy’s day so much.
He also hopes this will bring awareness to parents to talk with their children about bullying.
"I’m hoping that every parent will sit with their child and talk to their child about being bullied or bullying someone else," he said. "As Cassidy’s dad it devastated me, No parent wants to see their child going through it and as Cassidy’s dad, I wouldn’t want to be the parent making someone else’s child feel like that."
Warner is inspired by his little girl.
"I’m many, many years older than my daughter and she’s definitely my hero."
