Iggy Azalea says childhood bullying led her to "self-sabotage".
The 29-year-old star admitted her high school experience meant she found it difficult as she got older to read people and "tell the difference" when someone was being "constructive" rather than cruel.
In an interview with RuPaul, she said: "There were people around me that I worked with who were like, 'We love you and we think that you self-sabotage yourself'.
"I knew that it was true and I think a lot of it was because I got bullied in high school and made fun of because I was always very ridiculous and over the top.
"So it was hard for me in my adult life to be able to tell the difference between somebody being critical and constructive, and somebody bullying."
The 'Fancy' hitmaker spent time at a mental health retreat in Arizona, and she was glad for the experience of the "intensive workshop".
