As children return to school this week a new survey reveals that many of them are worried about the start of the new term and the threat of bullying.
A return to school survey of more than 1,000 eight to 15-year-olds carried out for Barnardo's by YouGov showed that almost three in every 10 children worry about changing schools, class or teachers, and for 11-year-olds who are moving to secondary school this increases to more than half.
More than half of eight-year-olds said their friends had experienced someone kicking or punching them.
The charity Barnardo's launched a television advertising campaign on Thursday on the themes of anxiety and bullying which highlights the importance of mental health support services for children and young people.
Among those backing the campaign is 15-year-old Casey-Jane Bishop from the Cynon Valley who struggles with severe anxiety but is now facing her fears to give young people like her a voice.
Casey-Jane is one of three young people elected to the Welsh Youth Parliament to represent Barnardo's Cymru and, like the charity, has called on schools to do more to reduce bullying and promote young people's mental health by offering them safe spaces where they can talk about their concerns.
Barnardo's advert uses the images of hyenas following a girl to school, circling her in the playground and appearing on her phone in her bedroom to convey anxiety.
Casey-Jane has been left suffering anxiety attacks which can strike at any time after years of being physically and mentally bullied, sometimes going home from school bruised and scratched.
Her mother spoke to the school and after that teachers stepped in to try to prevent further attacks and she was pleased to move up to secondary school in a new area away from the group who had bullied her.
But when her parents split up she found she was once again a target for bullies and it is only now as her peer group have turned their attentions to exams that things have settled down for her.
She has been helped by the Child and Adolescent Mental Health Service (CAHMS) and Barnardo's Resilient Families project.
Barnardo's has published its best tips on how to help your child feel ready for the start of term and settle in.
