Sophie was just 17 when she was contacted online by someone she believed to be a boy of her own age.
Having just split from her boyfriend, Sophie - not her real name - admits she was feeling low and lacking self-confidence, so welcomed his attention.
"He told me I was pretty and we chatted on and off for about a month or so on various social media platforms," she says.
He asked her to send him some pictures, which she did. "I didn't think much of it," she says.
He then told her she could make money from the pictures, and asked for more, including sexually explicit shots.
"So I began sending him pictures of what he asked for. Before too long, it was videos and I was in way too deep," she says.
Sophie realised something was amiss when people began to contact her to say they had seen the videos.
The "boy" asked her for more photos and video, this time of her with others, and she never received any money.
"I felt like I was in a mess and it was all too much," she says.
