AceShowbiz - Kanye West experimented with scream therapy in a bid to help boost his self-confidence.

The "Stronger" singer admitted his wife Kim Kardashian encouraged him to try out the unconventional therapy last year as part of a staged intervention, after a series of life events - including Kim's gunpoint robbery and Kanye's hospitalisation for temporary psychosis - had left the rapper "very low".

"Keeping Up with the Kardashians" star Kim enlisted the help of motivational speaker and life coach Tony Robbins, who recognised Kanye's lack of self-confidence immediately, but the star has now confessed to finding the whole experience uncomfortable.

"I was so self-conscious about the nanny and the housekeeper that I didn't want them to hear me screaming in the living room," he told The New York Times. "I think that that's such a metaphor of something for the existence of so-called well-off people that they're not really well-off - they won't even scream in their own house."

Despite his reluctance, Kanye continued with the treatment, which saw him getting into a warrior pose and screaming as loudly as he could.

The remedy, also known as primal therapy, is believed to release repressed anger or frustration, but the 41-year-old says the experience didn't have the desired effects.

"I still felt self-conscious," he sighed, adding it hadn't been an instantaneous fix. "I didn't have my confidence back."

The dad-of-three further opened up about his reasons for considering the therapy, revealing he regularly battles with suicidal thoughts.

His comments echo the lyrics on his "Ye" album track "I Thought About Killing You", which include the lines: "Today I thought about killing you, premeditated murder/I think about killing myself/And I, I love myself way more than I love you."

"I've thought about killing myself all the time," Kanye stated. "It's always an option. Like (comedian) Louis C.K. said: 'I flip through the manual. I weigh all the options'."
