Tallulah Willis is "starting to feel OK" about herself after seeking treatment in rehab.
The 20-year-old star, who was diagnosed with body dysmorphic disorder when she was 13, checked into a treatment facility for 45 days in late July to battle depression and drugs after her sister Scout Willis, 23, "forced me to see what I was doing."
Asked why she decided to seek help, the fashion blogger, who is Bruce Willis and Demi Moore's youngest daughter, said: "There wasn't a huge, horrible moment, but I knew I needed to go take care of myself."
Tallulah became her "own worst critic" when she entered her teens.
She told the February issue of Teen Vogue magazine: "I recall very specifically I was in a New York hotel room when I was 13 (before social media was such a huge thing), looking at a photo of myself online. I broke down in tears as I started to read the comments. I thought, I am a hideous, disgusting-looking person. I might be nice and I might be kind, but I'm a really unattractive human being.
"In that moment, a switch flipped. It wasn't about the anonymous cyberbullies--I became my own worst critic."
The blonde beauty started abusing drugs when her "depression became overwhelming" in college.
She said: "I was so removed from my body and from my mind that it was like I was living in a cardboard replica of what life should be. Not even so much because I was doing drugs but because I was so sad and so unhappy."
While Tallulah is on the road to recovery, she admits it isn't easy.
She explained: "It's not night and day--it's not like now I completely love myself and I have no problems. That isn't how it works. But there are the starting points of that, and that's really exciting. I'm growing every day and breaking old patterns."
