Marjama, 28, said that playing Major League Baseball has been his dream since he was a child.
"I always wanted to play professional baseball," Marjama said, adding that it has been "a goal I’ve always looked forward to ever since I was a little kid."
He added that he played baseball starting in Little League and throughout middle school.
"I kind of had baseball taken away from me my junior year of high school," he said. "I wasn’t able to play, unfortunately, because of my eating disorder and hospitalization."
Marjama said that looking back, he thinks his eating disorder originally started when he was around eighth grade, saying, "it progressed all the way through my junior year of high school."
"I was definitely getting into an attraction to girls," he said of that time. "So my way was thinking about it was ... if I’m going to get a girlfriend, I’ve got to get a six pack, and so I thought it I didn’t eat anything, well I wouldn’t get any fat, and then if I worked out a ton I would get big and muscular."
Soon, he said, his obsession with his body image began to spiral out of control and consume him.
"I started just restricting my diet, just overworking," he said. "I put a stationary bike in the shower, and [would] ride until I would pass out."
Marjama said he "progressively got into anorexia" and "ultimately into binging and purging and bulimia."
He hit "rock bottom" during 11th grade, when he said he was admitted into an in-patient program, where he stayed for five days.
"That’s when I kind of knew, like, I was a threat to myself," he added. "That’s when it really hit home that maybe I really do have a problem."
In addition, eating disorders will affect approximately 10 million males in the U.S. at some point in their lives, according to NEDA.
A little over 10 years after his darkest days in high school, Marjama said he is now in recovery, and he isn't taking his success or his platform for granted.
He is opening up about his battle with an eating disorder in a new documentary short film for Uninterrupted, NBA star LeBron James' multimedia platform for athletes. Marjama hopes to shed light on the topic, especially for fellow men who may be struggling.
"If I can maybe affect one person that doesn’t have to have their hopes and dreams taken away from them because they’re suffering from an eating disorder," he said. "And they’re able to follow their hopes and dreams, that’s all I really want."
