"And I was like, 'I don't even remember how I did it'."
Curtis, who was imprisoned during this period, recounted, "I knew what was happening. She wouldn't listen to me. I'd try and bring her into line, and it was just ridiculous."
Jacenko also admitted that she turned to medical help after she "reached a breaking point" - having considered taking her own life.
"I was very close to standing at The Gap. I wouldn't have coped."
"The only thing that stopped me was the fact that they [her two kids Hunter, four, and Pixie, six] needed me."

Since removing the lump back in 2016, Jacenko has been given the all clear.
