A grieving Gold Coast mother has spoken of the harrowing moment she missed her daughter’s desperate phone calls for help, before the 13-year-old took her own life after months of bullying.

Wiping back tears, Sharlene Scott told 9NEWS she felt sick to her stomach when she found a series of messages and missed calls on her phone from her daughter, Emily Stick.

“I got a message that night from Emily saying ‘I’m going to kill myself’,” Ms Scott said in an exclusive interview with 9NEWS.

“But I never saw it until it was already too late.”

Ms Scott said she felt like a “hopeless” parent after her “fun-loving and caring” daughter died a month ago.

The bright and bubbly army cadet “who always had a smile on her face” took her own life after months of physical, verbal and online abuse.

The cruel torment followed Emily everywhere, with the teen hiding out in school toilets to avoid going to class with her bullies.

“Even her having those thoughts to kill herself at 13, it was scary,” Ms Scott said.

“I just think they were jealous of her life.

“She couldn’t escape it, they followed her everywhere.

“She had a couple of girls tell her they were going to bash her until she wasn’t breathing any more.

“Thirty of them tried to attack her – male and females.

“She was too scared to even go to the bus stop.”

While the family said police were investigating Emily’s death, they don’t believe any of the bullies will face punishment.

“I don’t believe there’ll be anything criminal that will come of it,” Emily’s aunt Belinda Watson said.

“The main bully seemed really remorseful the next day, burst into tears and said it was all her fault.

“Then you had some that were laughing ... like it was a big joke.”

Ms Scott mother is calling for tougher punishments for those who cyber-bully, with this message for Emily’s tormentors: “I hope they’re happy. I hope they feel good about themselves.”

“What did she do so bad that you just had to keep bullying her to the point that she took her own life?” Ms Scott asked.

Emily’s death comes months after Australia mourned the suicide of 14-year-old Northern Territory girl Dolly Everett, which re-ignited a national conversation about cyber bullying.

Tomorrow, a Senate committee is expected to hand down its findings following an inquiry into whether perpetrators should attract tougher criminal charges.

“There needs to be consequences – otherwise they just don’t stop,” Ms Scott said.

“Emily’s not the first child and probably won’t be the last at all and we need to stop it somehow,” Ms Watson said.
