Rosalie's parents plan to take her off life support on Monday evening, reports CBS, and donate her organs.
"My daughter is a victim of bullying ... the world lost a treasure", Charlene Avila wrote on a GoFundMe page after the death of her child, Rosalie Avila, an eighth grader at Mesa View Middle School in Yucaipa.
"And it said, "Sorry, Mom, you're gonna find me like this", the grieving father said.
"Sorry, Mom and Dad".
'I remember a couple nights she'd come home, telling me that the kids are calling her names about her teeth, ' he said.
"That's my daughter... it's so heartless, so mean to do that and it's not amusing, it's not amusing to see that image of your daughter and to be mocked like she's crap and she's not".
But the bullying that drove Rosalie to try and take her own life is now targeting her parents, Freddie and Charlene Avila.
"They told me I was ugly today", father Freddie recalled reading from Rosalie's journal, according to the outlet.
"I'm here today angry because my daughter is no longer with me and angry because of these bullies continuing to bully", Mr Avila told Fox 11 News.
Rosalie's parents knew about the bullying, yet they did not know how to make it stop.
The parents received a meme on social media with Rosalie's face that read "hey mom". "Tuck me in THIS", the caption read, with an arrow pointing to a grave. The Avila's also believe the school could have done more to prevent this tragedy, and want the district to act to prevent bullying.
Freddie added: "I did everything I'm supposed to do as a father, and these people did not respond, because those bullies are still at the school". Charlene and Freddie are still trying to come to terms with what happened to their precious daughter, and they admit they "don't know" what ultimately went wrong. "I think kids don't have the maturity to handle it".
Over the past two months, her parents noticed their daughter had become more reclusive, and put her in counseling after discovering she was cutting herself, Avila said.
'No one can fathom the heartbreak and confusion that we are certain many of our students and families are feeling right now, ' the school said in a statement, according to NBC.
Her family is now raising money for her funeral expenses with GoFundMe.
On Friday, her family made the hard decision to take her off life support.
"She loved the beach & liked going out to the snow", the girl's mom wrote on GoFundMe.
Then they started getting abusive messages themselves. She was a lovely person inside and out. She was a handsome person inside and out. She was daddy's girl and mommy's princess.
Rosalie Avila hanged herself in her room on November 28 and was rushed to hospital, where she was declared brain dead a day later. She wanted to be a lawyer and wanted to help the world to be a better place.
