The 49-year-old Australian actress is single again following the breakdown of her marriage to Sacha Baron Cohen and she's admitted her life has totally changed and she's trying to adapt by staying as "as buoyant as possible".
She told Harper's Bazaar magazine: "I've had a tough couple of years, but I'm making it through. I'm really excited for the next chapter.
"I'm refocusing on my career, because previously I was very much focused on my kids, which I still am, obviously, because they're my true love. But I'm enjoying tackling work again."
She added: "That's been one of the benefits of a challenging situation: the luxury of asking myself, What would I like to do professionally and privately? ...
"I'm trying to remind myself of my new identity as somebody outside of a partnership and to stay as buoyant as possible. Any time there's change, it's hard to adapt. But hopefully I'm doing an okay job."
The former couple - who have three children together - announced their split in April and in May revealed their divorce had been finalised, allowing them both to move forward.
In a joint statement posted on Instagram, the former Hollywood couple explained: "Our divorce has now been finalised. We are proud of all we've achieved together and, continuing our great respect for each other, we remain friends and committed to co-parenting our wonderful children.
"We ask for the media to continue to respect our children's privacy."
Fisher previously called her divorce the "most difficult thing" she's been through, but insisted at the time that she and the Borat star remained focused on their children. She told The Sunday Times newspaper: "I've learned so much about myself in the process. I never imagined my family being separated, but we are committed and loving parents ...
"Kids are the most important thing, and you want them to really feel safe and loved. We are building a new, healthy version of what our family looks like and putting as much care and love into it as possible."
