Heatherton, 27, wrote candidly about the doubts she feels in the modeling industry in an Instagram post Thursday night.
"I was struggling with my body image and the pressures to fulfill the demands of perfectionism upon me," Heatherton says. "I am not perfect."
But she was able to move past it, and grow from there.
The breakdown to breakthrough moment in my life has allowed me to become the truest version of myself. In my moment of “failure,” I stood in the face of adversity. I was struggling with my body image and the pressures to fulfill the demands of perfectionism upon me. I am not perfect. Through this struggle, however, I found the strength to love myself. I stood in my power. I thought of one of my favorite quotes, “Nearly all men can stand adversity, but if you want to test a men’s character, give him power” - Abraham Lincoln. I look back on that moment now, and I embrace it. This feeling I once perceived as “failure” was, in truth, a powerful awakening for me to stand behind my purpose in life. I stepped away from hiding behind a fabricated version of myself. I no longer put actions behind my fears and insecurities. I made a choice to redirect my energy to be a catalyst for change. To create a channel for women to become the truest versions of themselves, along with me. (Stay tuned for more...) In the end, if you aren’t being true to yourself, then what the fuck is the point. #rebelwacause #empowerment #womensempowerment#empoweredbyyou
And now she wants other women to join her in support.
"I made a choice to redirect my energy to be a catalyst for change," Heatherton says. "To create a channel for women to become the truest versions of themselves, along with me. In the end, if you aren’t being true to yourself, then what the f--- is the point."
The model, who previously dated Leonardo DiCaprio, is also devoted to her Ballet Beautiful workouts to find her strength.

Heatherton works out almost every day for an hour-and-a-half, but she knows now to give her body time to heal after each intense sweat session.
“Your ligaments can only heal through rest, and you have to rest if you want to see the results of all your hard work,” she said.
