A drinking buddy of Lanza’s told the Daily News that her son Adam had long been troubled and rarely came up in conversation.

“She just looked down at the glass and said, ‘I don’t know. I’m worried I’m losing him,’” said the bar pal, who did not wish to be named, of the ominous conversation at the watering hole My Place in Newtown, Conn.

“She said it was getting worse. She was having trouble reaching him.”
