Emma Stone [1] is using her star power to shed light on some very important issues. While promoting her film Battles of the Sexes [2], the Oscar-winning actress opened up about her lifelong battle with anxiety when she stopped by The Late Show With Stephen Colbert [3] on Tuesday night. After gushing about special guest Hillary Clinton during the show, the host pulled out a drawing Emma made during a therapy session when she was 9, which showcases a stick figure of herself and a small green monster, with the text: "I'm bigger than my anxiety." "I was a very, very, very anxious child, and I had a lot of panic attacks," she explained. "I benefited in a big way from therapy." See her heartwarming video above.
