(CNN) -- Edgar Hernandez didn't expect to learn that he was pre-diabetic at age 16. 

When his mother burst into tears at the doctor's office, it hit him hard. He was 370 pounds and couldn't stand to look at himself. 

It was tough being a fat kid, but things became unbearable in high school. Edgar was seeing a therapist for depression symptoms. He was frequently bullied in gym class. Kids would point at his "fat wobbling everywhere," especially as he struggled to keep up. 

"I tried my best to ignore it. But there were times when I just gave in and started crying," said Edgar, who lives in a suburb of St. Louis and is now 18. 

Everyone in his family had a weight problem; his parents developed type 2 diabetes in their forties. But Edgar was the biggest. 

"He would eat two really big burritos or sandwiches a day, packed with cheese, sour cream, a lot of bread, butter," his older brother Mario said. "He would be watching TV, playing video games." 

After receiving the sobering blood test result at the doctor's office, Edgar went home and cried. And then something new happened: He owned up to his weight problem. 

"It was time to stop blaming others for my choices and make a choice to take responsibility," he said. 

He dried his tears, threw on his jacket and began jogging. He only got about half a mile before he stopped and threw up. 

That was a year and a half ago. Edgar, who is 5-foot-9, went on to drop nearly 200 pounds. He now weighs 185 pounds. He has traded his double-XL shirts and size 48 pants for medium T-shirts and 33-inch pants.
