All this week on Heart, we're focusing on bullying.
It's because this week is national anti-bullying week.
We're speaking to people who have experience of dealing with bullying or supporting victims.
People like 15 year old Charlie Bowden, a cyber-mentor at Linton Village College, anti-bullying ambassadors from Dogsthorpe Primary School and Lara Jaffey, the manager of the charity SexYOUality, which supports lesbian, gay and bisexual people in Cambridgeshire who are abused because of their sexuality.
On Friday, we'll hear from the Cambridgeshire-based Olympic swimmer Mark Foster and his experiences of bullying, and also the manager of a Cambridge charity called Cogwheel and the work it does to support people who are bullied at work.
Check out the links below for advice and support for victims of bullying.
