It’s actually been terrible. "Not just comments, but people making full on videos trash talking my body and my techniques as a certified fitness instructor. "You may not know it, but when things get bad, I try my best to hold back my tears and tighten my mouth so that I don’t frown. "But sometimes, it gets to be too much. So I break." Cassey also edited an Instagram photo to show that even "the perfect body" receives backlash online. Speaking to People magazine about her decision to share the video and photo, Cassey said: "The goal is to show that cyber-bullying and mean comments really affect people, and to think before you say something". I hope that people do the exact opposite after seeing this video, which is enlighten everyone around them with positivity."
