Sienna Miller has revealed how therapy has helped her take control of her life and help with issues of loneliness and isolation.
The actress, who is best known for her roles in Layer Cake, Alfie and American Sniper, said the analysis she went through was a terrifying experience.
She told Porter magazine: "It's terrifying but extraordinary. It's 10 years of therapy in a week. I got back a week ago. It takes a while to settle.
"It's focused on Freudian analysis, which is basically how behaviour patterns are all learned, how you can trace them all back to either parents or surrogates, then you kind of let go and examine who you would have been if you hadn't taken on all these negative traits.
"There's an immense amount of space in my head and there is no f*****g noise in it for the first time. All that noise has just gone."
Discussing why she sought out treatment, she said: "I just got to a point where I just felt... I didn't understand why I was, I couldn't dig myself out, I couldn't make decisions, I felt pretty assaulted by life and not in control...
"Without being really indulgent, I think as you get older you have to really cultivate your mind and have a deep understanding of self, otherwise you just become lonely and isolated and unsatisfied and unfulfilled, and however your perfect little life looks on paper, there will be a sense of unfulfilment if you haven't explored the nature, the very depths of who you are."
Miller struggled to deal with press intrusion into her life during her high-profile relationship with former partner Jude Law, who she says she still cares about "enormously".
Looking back on that period now, she said she is grateful she made it through.
She told the magazine: ""Thank God I actually survived it. I watched that Amy Winehouse documentary and, not to compare myself, but there was footage that... it was a similar time, and you just lose your mind.
"It basically perpetuates all the behaviour that it wants. It creates what it can feed off. It's a really toxic animal. So you start to implode and then there's more footage and you can't help but... I couldn't cope but it's resilience that kicked in. And no heroin addiction, thank God."
Miller, who recently split up from fellow actor Tom Sturridge, the father of her daughter Marlowe, also admitted she would like to have more children, adding: "I'm suddenly feeling very broody for more babies, and my daughter's desperate to have a sibling."
