The father of the 35-year-old Manhattan woman found dead in her car of an apparent suicide is struggling for answers while describing his daughter as 'my whole world.'
Ariel Campbell, a psychotherapist, was found dead in the back seat of her Jeep on Sunday after ingesting hazardous chemicals.
DailyMail.com can reveal that Brandt lime sulfur – often used to kill pests on plants and fruits – was found in her passenger seat and had been with mixed with an unknown substance to form hydrogen sulfide gas, a deadly chemical if ingested.
Her father David Campbell, 75, said it's possible her mother Elizabeth's death last year was a factor.
'I know she had a great deal of difficulty dealing with the loss of her mother and I can only imagine that's what drove her to this,' said Campbell, the former CEO of Global Minerals and Metals Corp.

Ariel, a licensed clinical psychotherapist who specialized in treating anxiety and mood disorders, didn't disclose to her family why she might take her own life.
'She left no note in her apartment or with her, so I don't know much about what happened and what's behind it,' Campbell said.
'All I can tell you is that Ariel was my only child,' he continued in describing the tragic loss.
'My wife and her mother passed away last year, and the two of them were my whole world. And now with her mother gone, Ariel was my entire world. And now she's gone. Both my wife and I could not possibly have loved her more.
'And to avoid breaking out in tears, that's all I can really tell you.'
The apparent suicide happened inside her parked Jeep at East 56th Street and Sutton Place, near the East River, about a block from the building where she previously lived with her family.
Ariel had a privileged upbringing. She had gone to the private Dalton School and then on to Cornell University where she earned a Bachelor's Degree in psychology according to her LinkedIn profile.
She then went on to earn a PhD in psychology at the Ferkauf Graduate School of Psychology, a division of New York's Yeshiva University.
She said on LinkedIn she was a 'licensed clinical psychologist specializing in cognitive behavioral therapy with adults, adolescents and children.
'Areas of expertise include treatment of anxiety disorders, depression, OCD and trauma,' she wrote, adding she had 'significant experience working with patients of all ages, presenting disordered eating, emotion dysregulation, interpersonal difficulties, behavioral problems and general difficulties coping with typical life stressors.'
Two NYPD officers and an EMS worker sustained minor injuries at the scene, and one was transported to a local hospital in the aftermath

The odor was reported to smell like rotten eggs.
Hazmat-clad emergency service members descended on the scene, closing down the street as first responders could be seen using Geiger counters to measure radiation levels in the area.
The area remained cordoned off Sunday evening, after two NYPD officers and an EMS member suffered minor injuries. One of them was taken to a local hospital in the aftermath.
Authorities said an array of liquid chemicals, now confirmed to be lime sulfur, were found inside the car, the combination of which is believed to have killed Ariel.
