Amanda Seyfried candidly discusses her private and years-long battle with 'really extreme' OCD
Moderator - Tomas Kauer 
Amanda Seyfried has opened up about her battle with obsessive-compulsive disorder.
The Mean Girls star, 40, told Vogue in a candid chat that her OCD is "really extreme" and that she has been on medication for it for years.
Seyfried, who is celebrating the release of her new film The Housemaid with Sydney Sweeney, said that she was 19 years old when she found out she had OCD.
"I was living in Marina del Rey at the time, shooting Big Love and my mum had to take a sabbatical from work in Pennsylvania to live with me for a month," she explained about her diagnosis at the time.
"I got my brain scans, and that's when I got on medication—which to this day, I'm on every night."
It comes after the actress revealed she was left a little confused by Timothée Chalamet's shoutout to girlfriend Kylie Jenner during his acceptance speech at the Critics Choice Awards earlier this week.

In his speech, the Dune and Wonka star, 30, said: "Thank you to my partner of three years. Thank you for our foundation. I love you. I couldn't do this without you. Thank you from the bottom of my heart."
"I love you," Jenner sweetly replied.
It was Chalamet's use of the word "foundation" that confused Seyfried. 
Underneath an Instagram post of the moment shared by Evan Ross Katz, the actress admitted she got mixed up.
"OH not like a foundation/charity," she commented underneath.
"I was curious about that."
Her comment got more than 1,200 likes.
Fans on social media were also shocked, not realising the actor and reality TV star, influencer and beauty entrepreneur Jenner, 28, have been dating for three years already.
"My first thought was – wait it's been 3 years? Lol," another person wrote underneath Katz's post.
