“Katie is constantly scribbling notes in her diary. It’s something she says is really helping her to cope,” an insider reveals to OK!. “She actually got the idea from one of Oprah Winfrey’s shows discussing the value of keeping a journal. Writing down emotions with a pen and paper is proven to help the brain process stressful situations, and right now Katie is really struggling with anger, sadness and guilt. She's writing about everything from her fun times with Suri to the difficulties with Tom.”
