Black, who is currently on tour after releasing her EP, Rebel, said she's now using her experience to help others.
"People still say hateful things about me, but it happens less often these days," she confessed. "Internet bullying is not inevitable, if we allow ourselves to learn a bit more and stand up for others and what’s right."
"Nobody needs to suffer in silence, like I did, for so many years. Talk to someone who can help, whether that’s a friend, a trusted adult or a mental health professional," she concluded. "Whatever a bully is saying about you is wrong. It didn’t feel that way when I was 13 and people were writing about how awful and undeserving I was, but I now know they were wrong."
ET recently sat down with YouTube star Bethany Mota, who also opened about being bullied. Watch below.
