Los Angeles: Actor Wentworth Miller, protagonist of American TV series "Prison Break", says he battled with suicidal depression. The 43-year-old shared on his Facebook account that he was once suicidal and addressed a meme highlighting his past weight gain, reports people.com. "Today I found myself the subject of an internet meme. Not for the first time. This one, however, stands out from the rest. In 2010, semi-retired from acting, I was keeping a low-profile for a number of reasons. First and foremost, I was suicidal,” Miller posted. "I was looking everywhere for relief, comfort, distraction. And I turned to food. It could have been anything, drugs, alcohol, sex. But eating became the one thing I could look forward to. Count on to get me through. And I put on weight. Big deal,” he added. The actor also said he was “ashamed and in pain” at the time, and suffered in silence, adding that he even contemplated suicide. "Now, when I see that image of me in my red t-shirt, a rare smile on my face, I am reminded of my struggle. My endurance and my perseverance in the face of all kinds of demons. Some within. Some without. Like a dandelion up through the pavement, I persist,” he added.
