Scott Disick told Khloe Kardashian he wanted his "life to be over" in a tearful phone call.
The 32-year-old reality star - who has endured a stint in rehab since splitting from long-term partner Kourtney Kardashian last July - texted his former girlfriend's sister to say he couldn't "take it any more", prompting her to call and check on his welfare.
Calling Scott while her sister Kim Kardashian West, half-sister Kylie Jenner and mother Kris Jenner were on the line, Khloe asked: "Why did you send me that message? Khloe asks. "Are you OK?"
Scott replied: "I just... I just can't do this."
After the worried women say they want to call the police to check on him, Scott said: "I just can't keep doing this without my family."
Khloe replied: "I understand, but try to get better. You can't just give up, OK? Where are you? Scott? I can't understand you I wish I could."
Scott then went on to speak of how much he misses Kourtney, the mother of his kids Mason, six, Penelope, three, and Reign, 13 months.
He continued: "I'll never f***ing meet anybody more beautiful than her, and I love her. But she doesn't love me."
Khloe reassured him: "She definitely does love you, but she wants you to get better and love yourself."
Scott replied: "My life is officially over, I just want it over. And I just wanted you to know."
After the family established Scott was in New York, Kris called his friend Chris Reda and asked him to go and check up on the troubled star.
Kris told him: "If you cannot get in his room I want you to text me and I want you to call 911 immediately, no joke, text me and tell me what happens."
Meanwhile, Scott was still confiding in Khloe.
In scenes aired on last night's (17.01.16) 'Keeping Up With the Kardashians', he said: "I just can't f***ing get it together. I just can't f***ing handle it."
However, Chris then called to say he was in the room with his friend, and Scott abruptly ended his call to Khloe.
Luckily, the family later got more peace of mind about Scott's welfare when Chris called again to reassure them he was OK.
