It's that time of year again. The Emmy Rossum nude sex scene in Shamelesssummer holidays have drawn to a close, and one million children up and down the country will be getting ready to go back to school this week. But, over half of those children will be affected by bullying, according to an anti-bullying campaign launched today.

As part of the Diana Award #Back2School campaign people are sharing their old school photos along with advice for going back to school to encourage young people to report bullying to teachers.

Channel 4 presenter Cathy Newman kicked off the campaign by sharing her own school photo taken when she was around 8 or 9 years old.

"I've got sticky-outy teeth that I became really self-conscious about. I've got the neat little plaits, I look very keen and eager (I was)," Newman explained in a YouTube video.

"I guess that's why I started getting a little bit teased at school. Because I was a really girly swot," Newman added. She went on to say that things got "tougher" as she progressed through secondary school, and she wishes that she had reported some of the things that happened to her.

"You've got to report it. Schools are primed now to listen to your experiences, and to take action if some action is needed," she said.

People have been following in Newman's footsteps by sharing their photos and words of wisdom on Twitter.

"Remember to talk to a friend or teacher," wrote one person.

Newman also shared the advice she has passed on to her own young daughters.

"Be proud of who you are. Be proud of being an individual. If you're a little bit different, that's a badge of pride," she said.
