The actress departed her role as Sarah-Louise Platt in December 2007 and has since gone on to appear on Strictly Come Dancing and Waterloo Road. Speaking to What's On TV, O'Brien insisted that although it was a hard decision to make, she was glad that she had left when she did.
"Leaving Corrie was the hardest decision I ever made, but it was the right one," she said. "I'm really glad I've had the opportunity to do different things. I still watch the show occasionally and get sucked in instantly."
She continued: "I'm currently doing the Strictly tour with my dance partner Jared Murillo - he has become a great friend and we are like a brother and sister gone wrong!"
Discussing what she would like to do next, the 27-year-old added: "After that a film would be lovely or maybe a period drama. I am looking forward to more acting roles this year, so bring it on!"
Waterloo Road continues on Wednesday at 8pm on BBC One.
