The 47-year-old actress was left devastated last month when her beloved father Antony Kidman passed away but she is finding writing a useful outlet for expressing her emotions.
She said: "I have two screenplays that I'm in the midst of forming.
"I've had a very, very rough few weeks and a lot of the way in which I express myself is through writing.
"I don't know if I'm any good, but it's somewhere I can seek solace."
The 'Paperboy' actress - who has daughters Sunday, six, and Faith, three, with husband Keith Urban, and Isabella, 21, and Conor, 19, with ex-husband Tom Cruise - says her father's death has taught her to "live in the moment" and try not to worry about things.
She added to Grazia magazine: "I've gone through a tragedy which has absolutely shattered our family.
"It's taught me to live in the moment because you never know what's going to happen. Dad lived like that. He would always say, 'Nicci, don't worry, be happy.'
"He was a psychologist. He was a giver. And that is what I hope he's given me and my sister. That's what we always say we will continue to do. We will live the way he lived. I had an incredible father."
