Chilean Miners 60 Minutes Interview: Victims Contemplated Suicide, Cannibalism (VIDEO)

Several of the Chilean miners heroically rescued last October after more than two months trapped underground sat down for an interview with Bob Simon of "60 Minutes," set to air this weekend.

Doctors say all but one of the 33 miners have experienced severe psychological issues since the ordeal. They lived in constant fear of death during their entrapment nearly a half-mile underground, contemplating suicide and even cannibalism. "I said to a friend, 'Well, if we are going to continue suffering, it would be better for us to all go to the refuge, start an engine and with the carbon monoxide, just let ourselves go,'" said Zamora, one of the workers interviewed.

Other miners described debilitating anxiety since surfacing four months ago. While attempting to reclaim their lives, some take medication, and others struggle to rebuild the relationships they once had with friends and family members. One man is constructing a wall around his home.

"Before I went in, I was a happy guy," Zamora said. "Being trapped, watching my friends around me die, rocks falling...the other me is still in there."
