And he received praise for his “courage” from his mother Lisa Curry after the show aired, who told him, “You know Jaimi would be so proud of you.”

As part of a tall order during Tuesday night’s episode, the rookies had to stand in front of their fellow competitors and talk about something they’re most ashamed of.

The 27-year-old ironman told the group he “never fully understood” Jaimi’s health battles with alcohol and an eating disorder, which claimed his life in September. last year at the age of only 33.

Jett said his sister struggled with mental health issues for 15 years before her death, and at one point he attempted to have a heart-to-heart discussion with her about it.

“To me, it was kind of fair, ‘Why are you doing this to yourself?’ And I never fully understood it, ”Jett said.

“There is one thing I said at his funeral. I’m not going to say it because it was very personal but I remember telling her the night she asked me… that question, and I told her the honest truth. And I hoped that was the harsh reality she needed – to hear it from her younger brother.

“But she’s gone now. I kind of regret not being there for her anymore.

Speaking afterwards in a face-to-face interview, Jett said his family, including famous Olympian parents Grant Kenny and Lisa Curry, have done all they can to support Jaimi in his struggles.

“We did everything we could as a family and to have Jaimi try to get her out of there, but unfortunately that wasn’t the case. She was told she was not going to turn 30. She arrived at 33, ”he said.

“For me, it was like you had the will to change your life and make a difference. But it’s me. I cannot speak for someone who has mental health issues because I have never been there.

Jett added, “Everyone has to do their best for the people they love, but when you can’t, it makes you question yourself. Like, ‘was I a good enough brother?’ “

As he sat down again, Jett was comforted by his fellow rookies where he began to shed a tear.

“It takes a lot to make me cry, but I cried at Jaimi’s funeral and the night she died,” he added.

“She’s my older sister. Of course I will miss her.

Jett was interviewed one-on-one towards the end of the episode, where he recalled his last goodbye with Jaimi.

“I remember my sister passed away in September, we were all sitting around the hospital bed with her, saying our last goodbyes to her. And I just remember seeing them (her parents) setting there, holding her hand, just thinking, “What more could we have done?”

“Mom said it perfectly, she was fighting a demon in her head. And unfortunately the demons got it in the end. She would beat a few and then others would come back.

“It was good in a way because it was almost like his suffering was over. So she fought for another eight and a half hours, nine hours between the last time I saw her and when they removed the life support.

“And that’s what she was, she was a fighter. From day one until the end. “

Jett’s mother Lisa posted a heartfelt message message on his Instagram account after the episode aired, addressed directly to his son.

“Jett, you gave us so much to be proud of the young man that you have become, for everything you do, the kind, humble, funny and caring person you are known for – that’s why people love you and this is why for dad and me our proudest moments are when we can tell people you are our son, ”she wrote.

“I know it took a lot of courage to say what you did and we all know how hard it is to say the words out loud, but you know Jaimi would be so proud of you – she does. has always been and she loved you so very much, always her little brother.Stay strong my beautiful boy.
