The PR guru didn't hold back, looking back at the tumultuous time where her husband was incarcerated for insider trading.
The mum-of-two confessed that during the 2016 period, she was out of control turning to drugs, partying and alcohol.
"I think I started living a life very quickly as soon as Ollie went to jail that was fast. And that was drinking too much and consuming things that I shouldn't have been consuming... I went rogue, basically."
"I would go out, and I'd come home at all hours of the morning. I basically lost my marbles."
There was even a time when the 38-year-old crashed her husband's car.
"I remember driving Ollie's car and parking it and then the next day going downstairs and looking at it, and it was all smashed up."
"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."
The interview also saw the mum voice the dark moments following her cancer battle.
“I said to him, It’s your fault. This is all your fault,” she recalled, even telling him “you gave me cancer.”
“I felt bad saying it, but, to be honest with you, at the time you know I was very resentful. I was resentful I had to I was resentful that I had to be on my own. I had to work. I had to look after the children.”
Since removing the lump back in 2016, Jacenko has been given the all clear.
