A 13-year-old boy from Staten Island, New York, took his own life on Thursday after being bullied by classmates at school.
In teenager Daniel Fitzpatrick's tragic suicide note, which was supplied by his parents to The New York Daily News, he claimed that his old friends at Holy Angels Catholic Academy had stopped talking to him and didn't like him.
"I gave up," Daniel, who was scheduled to start at Brooklyn's Xaverian High School in the fall, wrote on lined paper.
"The teachers either they didn't do ANYTHING!" he scrawled in the note.
Daniel's cause of death was hanging and the manner was suicide, New York medical examiner spokesperson Julie Bolcer confirmed to PEOPLE.
Daniel's father, also Daniel Fitzpatrick, posted a video to his Facebook page on Saturday to thank people for their support. In it, he condemns both the boys who allegedly "tormented" his son and the Catholic school that reportedly told him, "You'll be fineâ€¦ These things will pass" when the teen went to school officials for help.
Holy Angels Catholic Academy has not immediately respond to PEOPLE's request for comment.
"Thank you to all the people out there for your support and condolences, your thoughts and your shares," Daniel says in the Facebook video. "My son's story is now out there for the world to see and for the world to know the pain that he went through. I miss my son very much."
"No parent should have to bury their child. No child should have to go through what my son went through."
"To the parents of the boys that tormented my son, all I have to say is I hope you never have to feel what my family is going through right now. You get to hold your children every night and day for the rest of your lives and their natural lives. I don't get that anymore. Your little monsters took that from me and my wife," he continued.
Daniel's mother, Maureen Fitzpatrick told the Daily News she recalled her son saying he wanted the bullies – who he names in his suicide note – to "know what they did to me and how I feel."
Daniel and Maureen claim the "bullies" mentioned in his note embarrassed him at Holy Angels Catholic Academy – throwing balls at him in gym class and calling him names, according to the Daily News.
"Danny was always left out. He used to come up to me and ask me to get kids to play with him. The other kids would say they thought he was weird," Maureen told the news outlet.
And the parents allege that the school did nothing to prevent or to help the situation.
"He felt like the whole school knew what was going on and was laughing behind his back. They humiliated him," said Maureen.
These days, it seems like kids form in packs and single out a vulnerable victim to bully and emotionally break down. Where did this cruel and predatory behavior come from. It has been a growing problem, especially in the last decade. And so has child suicide. We are obviously responsible for our children's behavior and I would very much like to know where we went wrong. So tragic.
