The Keeping Up with the Kardashians star -- who's been married to Odom for four years and had always defended him up until several weeks ago -- admitted on Tuesday, "I'm trying my best," to get through these difficult times.
"Two years ago, Khloe thought they'd be married with two kids," added the friend. "There's still a lot of uncertainty."
Family sources told the New York Daily News in late August a Kardashian, 29, and Odom, 33, divorce is "imminent," and Kris Jenner was taking the lead on the process because Kardashian was "too emotional" and still hoped to "save" her husband.
"Kim, Kourtney and Kris want her to dump him. You can't live with a drug addict," a family source told the newspaper at the time.
