Ariel, a licensed clinical psychotherapist who specializes in the treatment of anxiety and mood disorders, did not reveal to her family why she might take her own life.

“She didn’t leave any notes in her apartment or with her, so I don’t know a lot about what happened and what’s behind it,” Campbell said.

“All I can tell you is that Ariel was my only daughter,” she went on to describe the tragic loss.

‘My wife and her mother passed away last year, and the two of them were my whole world. And now that her mother was gone, Ariel was my whole world. And now she’s gone. Both my wife and I could not have loved her more.

‘And to keep from breaking down in tears, that’s all I can really tell you.

The apparent suicide occurred inside his parked Jeep at East 56th Street and Sutton Place, near the East River, a block from the building where he previously lived with his family.

Ariel had a privileged upbringing. She had attended Dalton Private School and then Cornell University, where she earned a bachelor’s degree in psychology, according to her LinkedIn profile.

He then earned a doctorate in psychology from the Ferkauf Graduate School of Psychology, a division of Yeshiva University of New York.

She said on LinkedIn that she was a “licensed clinical psychologist specializing in cognitive behavioral therapy with adults, adolescents and children.”
