The young woman says her ordeal began when she was 14 and met a girl on an instant messaging app.

“I really had no friends, and I was really desperate,” Katie says. “At first, it started off with normal conversations, then Erin said if I sent her pictures of me in my underwear, she would send me gift cards to my favorite stores. Then it escalated to full on pictures of me being nude and videos. I thought it was very strange, but I kept doing it because I was really desperate.”

Katie says she sent over 1,000 pictures and 20 videos. “She kept harassing me, and I had no idea how to stop it. I hated myself and I was very depressed,” she continues.
