Actress Arielle Kebbel took to her Instagram account on Tuesday to share a message from her sister Julia Kebbel, who went missing in January and prompted a nationwide search spearheaded by her "Vampire Diaries" star sister.

In a post shared on Arielle’s account, Julia Kebbel, 36, said she had "psychotic break" due to her bipolar disorder. She was reported missing on Jan. 31.

Arielle shared the message from Julia to fans that read in part, “My name is Julia Kebbel. I have bipolar disorder and suffered a severe episode at the end of January 2018. It led to me experiencing a psychotic break from reality, during which time, I went missing with my dog, Cindy.”
