The Oscar-winning actress was so depressed after the relationship collapsed in 1997, she started the process of poisoning herself with carbon monoxide in her car.
It took an image of her mother, Judith, finding her body to stop her.
Berry tells Parade magazine, "I was sitting in my car, and I knew the gas was coming, when I had an image of my mother finding me.
"She sacrificed so much for her children, and to end my life would be an incredibly selfish thing to do. It was all about a relationship. My sense of worth was so low. I had to reprogram myself to see the good in me. Because someone didn't love me didn't mean I was unlovable. I promised myself I would never be a coward again."
