In the same interview , Perry also addressed her performance at the 2013 American Music Awards , which featured a Japanese " geisha " theme : " Even in my intention to appreciate Japanese culture , I did it wrong with a performance , and I did n't know that I did it wrong until I heard people saying I did it wrong . " On June 9 , Perry underwent a therapy session with psychologist Siri Sat Nam Singh , host of Viceland 's series '' The Therapist '' . The session attracted significant media attention as Perry became extremely emotional opening up about painful moments in her life , including a struggle with depression and suicidal thoughts . She talked about the shame she felt about that period of her life , which occurred following her 2012 divorce from Russell Brand , and led her to write the song " By the Grace of God " in 2013 . As Perry broke down emotionally , a member of her entourage suggested she end the session , but she declined . She also addressed her sexuality and the reasons why she went public with her feud with Taylor Swift
