The Maria Connor actress, who has been a Weatherfield regular since 2000, said recent events in her personal life have impacted on her decision.
Ghadie's father died in 2009 following a battle with cancer, while she separated from husband Matthew Smith last year.
Speaking to OK!, she explained: "I'd be very happy if I was still in Corrie in ten years' time. I think because of everything that has happened in the last few years I'm trying not to plan too much ahead. I am happy for each day.
"I often get anxious about things that never end up happening and it's such a waste of energy. I'm a terrible worrier but I'm working at that.
"They say that what doesn't kill you makes you stronger and I am definitely a stronger person now than I was back then."
The actress confirmed to Digital Spy in May that she has signed a contract extension which lasts until September 2013.
Ghadie also revealed the cast members to whom she is closest, divulging: "I'd say Jane Danson (Leanne) is my closest pal on set. I've known her for about 20 years.
"Likewise Alan Halsall (Tyrone), Andy Whyment (Kirk) and Ryan Thomas (Jason). We've all grown up together - they really are my second family. We look out for each other."
The 30-year-old also spoke about her past insecurities over her size in the wide-ranging interview, adding: "Ten years ago I was a bit heavier and it used to stress me out.
"When I look at old pictures of me now, I think I look fine - but at the time I was so self-critical. I wish I could have relaxed a bit more and not worried so much about my appearance."
