Nakeshia Thompson, from Austin, Texas, used to eat tons of fast food, comforted herself by eating, and admits she had “zero self-control.”

“Name any emotion and I could give a reason why food could help,” she wrote on Instagram. “I was obsessed. It was almost like the eating was out of my control.”

But by pushing herself to go to the gym, Thompson found new mental strength and control. “Embrace the struggles that the gym offers,” she said. “Absorb the idea that the outer edges of your comfort zone are where you now THRIVE.”
