(CNN)  -- At age 13, Hope Witsell struggled in middle school. Not because her class work at Shields Middle School in Ruskin, Florida, was challenging, but because Hope was being bullied. Her friend, Kyla Stich, told CNN that fellow students would "walk up to her and call her 'slut,' 'whore,' and they would sometimes, they would call her 'skank' and just be really cruel to her." Another friend, Lexi Leber, said, "We had to make like a wall, we had people surrounding her, and she had to be in the middle because people would come by and try to hit her and push her into a locker or something.
