She said: "I'm sitting still for a second. I got to take care of some dogs and get over this flu and then I'll think about some other things."
Zellweger previously took six years away from the spotlight in 2010, after she decided to prioritise her mental health.
In 2019, she explained: "I wasn't healthy. I wasn't taking care of myself. I was the last thing on my list of priorities."
The "Bridget Jones's Baby" star went to therapy during her time away from fame, and said the professional help allowed her to navigate her emotions.
She added: "He recognised that I spent 99 per cent of my life as the public persona and just a microscopic crumb of a fraction in my real life. I needed to not have something to do all the time, to not know what I'm going to be doing for the next two years in advance. I wanted to allow for some accidents. There had to be some quiet for the ideas to slip in."
Zellweger viewed her break as "important".
She said: "I had a good five-year period when I was joyful and in a new chapter that no one was even aware of. Six years. It was important, that time. It's a quieter life, and I love it."
