In fact, she says that in her recent round of interviews for her new Netflix movie, "First They Killed My Father," she has been "a little shy this time, because I am not as strong inside as I have been in the past."
Pitt and Jolie have yet to finalize their divorce but have agreed to handle matters privately for the sake of their six children.
"It's been difficult. I don't enjoy being single," the 42-year-old told the Sunday Telegraph. "It's not something I wanted. There's nothing nice about it. It's just hard. Sometimes maybe it appears I am pulling it all together, but really I am just trying to get through my days."
In addition to the separation from Pitt, Jolie revealed in July that she was recently diagnosed with Bell's palsy.
"Emotionally, it's been a very difficult year, and I have had some other health issues. So my health is something I have to monitor," she told the Telegraph.
Jolie has long been open about her health struggles, including her decision to have a preventive cancer.htm" id="ramplink_double mastectomy_" target="_blank">double mastectomy, which she wrote about in 2013 in The New York Times. But back then Jolie said that Pitt, now 53, was right by her side. Even as a single mother, Jolie said she's focusing on the positives in life as she moves forward.
"I am so happy I don't have cancer, and that if I do get it, it will be delayed for a few years. The exchange for that peace of mind is quite good," she added. "I think now I need to rediscover a little bit of the old me. I think we lose our way a bit. I have had a lot happen in my life, from certain people passing to health issues to raising the children. And it's been a very good time to absorb and develop and grow."
Pitt and Jolie met in the mid-2000s and after almost a decade together were married in 2014. They have three biological children and three adopted.
