"You just try to take it one day at a time, but sometimes it can feel like you're living 10 years in each one of those days," Lesley Fenton said.
Her daughter, Hayley-Ann Fenton, took her own life three years ago when she was 15 after receiving bullying texts from her boyfriend's wife.
"Life was going good, but when you lose a child it's like a bullet going through your heart," Mrs Fenton said.
Hayley met Pelesasa Tiumalu while working with him at McDonald's in January 2009.
They began a sexual relationship, and Hayley and Tiumalu told her parents that he was only 20 instead of 27. Six months later, Tiumalu's separated wife, Elina Tiumalu, returned with their almost 2-year-old son, and Tiumalu told Hayley he would leave her.
