Anderson Cooper and his mother, Gloria Vanderbilt, talked candidly about Cooper's brother's suicide in an interview set to air on Monday on Cooper's syndicated talk show "Anderson."

"When he went, I thought he was going to come back, but he didn't," Vanderbilt told Cooper. "There was a moment when I thought I was going to jump after him, but then I thought of you and it stopped me from doing that."

Cooper's brother, Carter Vanderbilt Cooper, committed suicide at the age of 23 when he fell to his death from the 14th floor terrace of the family's New York City apartment. Gloria Vanderbilt tried to stop him but failed. The journalist and talk show host gets visibly choked up while his mother talks about trying to cope with the death.

Cooper, 44, was 21-years-old at the time of his brother's death in 1988. Vanderbilt, a former fashion designer is now 87-years-old and was 64 at the time.

"You never get over it, but you learn to live with it," she told Cooper.

Vanderbilt is the only child of Reginald Vanderbilt, a railroad heir, and his second wife Gloria Morgan. Reginald Vanderbilt died in 1925, when Gloria Vanderbilt was 15-months-old. Morgan and Reginald Vanderbilt's sister, Gertrude Vanderbilt Whitney, fought for custody over Gloria Vanderbilt because Whitney believed Morgan was misusing of Gloria Vanderbuilt's trust fund. Whitney won the battle.

Gloria Vanderbilt married author Wyatt Emory Cooper in 1963. He was Vanderbilt's fourth husband and father to Carter and Anderson. Vanderbilt also has two sons from a marriage to her second husband, conductor Leopold Stokowski. Wyatt Emory Cooper died in 1978 during open heart surgery.

"You have survived so many things," Cooper told his mother. "This custody battle when you were 10 years old, the loss of your father when you were an infant, the loss of Carter, of my dad, your husband and so many others."
