Tish Cyrus is opening up about the "roughest" period in her life while grieving her mother and the end of her marriage to Billy Ray Cyrus. Tish's mom, Loretta Finley, died in 2020, just as she was experiencing marriage troubles with Billy Ray, from whom she filed for divorce from in 2022. At the time, she said she coped with her feelings of anxiety by "self-medicating" with weed. "I'd been in this relationship since I was 23 or 24," Tish, 58, recalled on the Wednesday, January 14, episode of "The Squeeze" podcast.
