Reese Witherspoon is looking back at a not-so-great moment in her life.

The “Little Fires Everywhere” actress appeared on former “The Good Place” star Jameela Jamil’s “I Weigh” podcast, where the two women spoke about Witherspoon's 2013 arrest.

“You apologized and shamed yourself in a way that was so f---ing refreshing to me,” Jamil, 34, told Witherspoon, 44. “I loved your apology.”

Witherspoon revealed that she's been in therapy since she was 16 years old.

“I definitely had anxiety. My anxiety manifests as depression so I would get really depressed. My brain is like a hamster on a wheel and it won’t come off," she said. "I’ve been managing it my entire life.”
