The second photo is a paparazzi shot that ended up in tabloids and magazines. In his revealing Facebook post, which you should read in its entirety, the actor explains that he was actually suicidal at the time it was taken.
"I've struggled with depression since childhood," explains Miller on Facebook. "It's a battle that's cost me time, opportunities, relationships, and a thousand sleepless nights. In 2010, at the lowest point in my adult life, 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."
Despite the pain the photo caused him, Miller writes that he's glad the photo is still around.
"The first time I saw this meme pop up in my social media feed, I have to admit, it hurt to breathe," he writes. "But as with everything in life, I get to assign meaning. And the meaning I assign to this/my image is Strength. Healing. Forgiveness."
