In an interview with Rolling Stone, Billie Eilish shared that she struggled with various mental difficulties as a teenager. When the artist was twelve years old, she faced dysmorphophobia (a disorder in which a person is overly concerned about his appearance and tends to look for defects in himself), which subsequently led to depression and self-injurious behavior.
Eilish noted that at that time she was engaged in competitive dancing and felt the most insecure. “I was always worried about my appearance and couldn't look at myself in the mirror at all. I felt I deserved the pain. Sometimes I see girls on my shows with scars on their arms and it breaks my heart. I told a few of them to just be kind to themselves. Because I know I was there,”the singer said, noting that psychotherapy helped her fight her disorders.
According to American experts, up to 30% of girls deliberately harm themselves in adolescence, without seeking to commit suicide. British researchers have come to the conclusion that at least one girl out of twenty faces dysmorphophobia at the age of seventeen or nineteen years.
