Scott Disick sparked concern from his fans after a clip where he broke down in tears over having "nobody" on Keeping Up with the Kardashians resurfaced.
The scene from the reality TV series - which ended last year - has been shared on social network Reddit this week, just days after the launch of the new show The Kardashians.
The clip, which originally aired in 2016, showed Scott, now 38, and Kourtney, now 42, shortly after they had separated, with him seen apologising to her family for his behaviour.
It opened with Khloé Kardashian, now 37, recalling Scott used to say he didn't have a family, so they gave him one, with her then asking him: "Why do you like destroy it?"
He responded: "I'm sure you guys have heard a lot of horrible things about me that I should have just been honest with, but I was too ashamed that I was gonna hurt everybody."
Scott - who has three children with Kourtney - said he had apologised to her numerous times but had never done the same to her family, including matriarch Kris Jenner, 66.
"I've never apologised to like all of you for letting all of you down and embarrassing you guys," he is heard saying in the footage, understood to have been filmed in 2015.
He says: "I understand I need to help myself way before I can help [Kourtney] or my kids. It's just been a really hard time going from having all of you guys to having nobody."
A longer version of the clip, shared by Entertainment Tonight, sees Scott acknowledge his "addiction issues" and say he would have taken his own life had it not been for his kids.
Scott has long battled alcohol and drug addiction, which spiralled out of control after the tragic deaths of his parents within three months of each other eight years ago.
Kourtney is seen in the extended version saying: "I think Scott always means it when he says that he wants to make a change. I just think he doesn't really know how to get there."
The resurfaced clip prompted numerous responses on Reddit, with one viewer writing: "This is such a real scene. The cycle of addiction and shame and all that mess."
"This scene was sad, I think Scott believed it when he would say he wanted to change but his self sabotaging tendencies always won out because of his addiction," said another.

"I feel like this scene is as real as gets to be honest and it makes me feel almost gross for watching such a vulnerable moment," commented another after seeing the clip.
The user who shared the clip on the platform had said: "This scene was depressing but so real." Others however felt that he was still manipulating the family in the scene.
This prompted a fan to write: "The man is flawed but that hurt is real. It's unfortunate he's manipulated so much that when this genuine emotion comes out some assume it's fake."
The Mirror approached a representative of Scott for comment.
