Sunday sees the fourth annual campaign to raise awareness of self-harm organised by charity YoungMinds and its partners.
Self-Harm Awareness Day has been held every year on 1 March and since 2012 YoungMinds has worked with ChildLine, selfharmUK and YouthNet to tackle stigma around self-harm and to raise awareness of the issue.
For the last two years the charities also worked with BBC Radio 1's Sunday Surgery with Aled Jones, helping produce a self-harm show that helped callers for whom self-harm was an issue.
Last year's campaign focused on distraction techniques as recommended by young people themselves and included suggestions such as going for a walk, listening to music and talking to friends.
This year the campaign has focused on the relationship between self-harm, social media and the online world. Organisers say they will be sharing the results of a poll of 2,000 children and young people on Self-Harm Awareness Day.
