Anderson Cooper on Lack of Closure After Brother's Suicide: 'It Doesn't Exist'

— -- Anderson Cooper and his mother, Gloria Vanderbilt, opened up to People magazine about losing Carter, Anderson's late brother and Gloria's son, 28 years ago in 1988.

Though it's been almost three decades since his suicide, Gloria and Anderson say there is no "closure."

"It doesn't exist. There's no such thing," the CNN anchor, 48, told People and EW Editorial Director Jess Cagle.

Carter died at just the age of 23, and Gloria, 92, says she relied on her other son after the tragic loss.

"Well, I remember the first Christmas we were together after it happened -- cause he died July 22 -- and we went to the movies," she said. Anderson echoed his mother, saying, "You can't help but come closer going through something like that, and, you know, it left us with each other."

He added the death of his brother is still fresh, "that sense of loss."

"It's stunning for me to think of how long ago it was that he died, that I've lived more of my life without him than I lived with him. That's incomprehensible to me. He's forever frozen in time," he said.

Carter died after jumping from his mother's 14th-floor apartment.

"When we were growing up, I used to imagine us being adults and being closer when we were adults and having families and kind of getting to know each other in a new way, and we never had that opportunity," Anderson told People.

Gloria said it helps to talk about her beloved son still to this day.

"I love to talk about him ... Because that brings him alive and it brings him closer and it means that he hasn't been forgotten," she said.

Anderson and his mother's joint memoir, "The Rainbow Comes and Goes: A Mother and Son Talk About Life, Love, and Loss," hits shelves April 5.
