Viewers of Keeping Up With The Kardashians know that Scott's long time relationship with Kourtney ended over the summer and the whole family have expressed concern at his excessive partying.
On last night's episode on the US, viewers saw Scott making a surprise return to the Kardashian household to address the family about his demons and just how low he had been feeling.
A choked up Scott told the family he'd been gutted seeing his kids – Mason, Penelope and Reign – in St Barts with the family, as he hadn't been there. "It was the first trip I haven't been on with my own kids," he said.
Scott added that being an only child and having lost both his parents last year had been "scary" and he felt utterly alone.
"It's sad because I considered everybody in this house my sister and my mum. In my mind, because of my insecurities, I feel like everyone is, 'No big deal, Scott is out of here, let's move to the next one.'"
He broke down in tears as he discussed his addiction issues, saying: "I should have been honest but I was too ashamed I would hurt everybody in this family, not just her. I have apologised to Kourtney a hundred times but I've never apologised to all of you for letting you down and embarrassing you. I realise I have to help myself before I can help her or my kids."
"It's not as easy as you think when you have addiction issues and I'm so ashamed I publicly embarrassed all of you. You did so much for me for so many years and it kills me to the point that I feel I can't make it up. I've never been as unhappy in my life. It's just terrible. If I didn't have those kids, I would kill myself. But I have them and I'm going to be here and I'm going to make it right for them."
Scott told the family he prayed that he could make it up to them one day, while the family told him they still loved him and cared for him and wanted him to get better, but also realised it wasn't healthy for Kourtney to use all her energies trying to help him.
