Christie Brinkley's 21-year-old daughter Sailor has admitted that she struggles with body dysmorphia. According to Mayo Clinic, "Body dysmorphic disorder is a mental health disorder in which you can't stop thinking about one or more perceived defects or flaws in your appearance \u2014 a flaw that appears minor or can't be seen by others. But you may feel so embarrassed, ashamed, and anxious that you may avoid many social situations." Sailor recently posted a series of photos with a caption that says she's learning to overcome these struggles. She wrote, "I've been so down on myself recently. Crying about my cellulite, letting the fat on my body ruin my day, getting mad that I'm not as skinny as I once was. The body dysmorphia and left over eating disorder tendencies have been coming in strong." Sailor says she is learning to love her body She continued, "As I come into myself as a young woman, my body shifts and changes by the month, the 'control' I felt I once had over it has been completely stripped away from me. Hormones, emotions, growing pains. I go on Instagram and scroll through photos of girls that look 'perfect'... shiny skin with not a bump to be seen, tiny little waist and thighs that look like chopsticks. And I compare myself, as if how someone on an app on my phone looks should directly correlate to how I feel about my body?"

I fuel my body with beautiful food. am so f------ LUCKY to have two legs and a healthy body that takes me through life. I'm so tired of thinking anything that makes up ME is something to be ashamed of." Sailor is following in her mother's footsteps to become a model and that career is likely what brought on these issues. Several years ago, she talked about her body dysmorphia and fought back against online bullies. Glad to hear that she seems to be on the right track these days and is feeling better.
