Sharon Osbourne says she was 'afraid and so alone' after abortion at 18

The star said she was 'terrified' to tell her parents

Sharon Osbourne is looking back on having an abortion at age 18.

The 68-year-old former reality star discussed becoming pregnant at a young age during a recent episode of "The Talk."

"I was terrified to tell my parents. Terrified," she recalled. "Especially my father. They would have been disappointed in me. I would have been a failure. My father would have just gone ballistic."

Osbourne chose to terminate the pregnancy and found herself "so ill" afterward.

"I had to tell my mother because she was calling the doctor and I had to tell my mother," said the host.

However, her mother's reaction wasn't quite as dramatic as she expected.

"She basically said, 'You did this, you've got to go through this on your own and you think you're such a big girl, you do it on your own,'" remembered Osbourne. "And I was like, 'OK I get it,' but you are terrified."
