Tammin Sursok

For all of you being bullied out there. This is me. Growing up I was overweight and spent most of my adolescence being bullied because of it. I definitely wasn’t the popular girl, but it didn’t define me. You can be ANYTHING you want to be in your life. It’s your choice which path you take. Don’t let other people’s words give you your self-worth. You are beautiful. I was beautiful. It just took me a long time to love myself. #thisisbeautiful

On 16 March 2016, Sursok posted a photo of herself as an adolescent on Instagram and revealed that she had been bullied because of her weight.
