The heartbroken sister of a straight-A student who committed suicide due to exam stress has launched a national campaign to prevent it happening again.

'Brainy' Daniel Long, 15, hanged himself in February 2017 after he developed acute anxiety whilst revising for his GCSEs.

He was discovered unresponsive by his heartbroken mum Emma Oliver, 43, who had rushed upstairs when she heard a loud bang coming from his bedroom.

Emma desperately tried to save him with CPR while a neighbour called 999, but Daniel was rushed to hospital where he was put on life support.

An inquest at Wakefield Coroner's Court on September 1 recorded a verdict of suicide.

He was pronounced brain dead and tragically passed away two days later.

'Cheeky chappy' Daniel became obsessed with revising for his GCSEs in January 2017 and spent up to four hours a night studying but still panicked he would forget the content.

After his death, Emma and Daniel's dad Andy Long decided to donate his organs.

His lungs, kidneys, stomach, pancreas and liver have now all had recipients.

Together with her mother Emma, Chelsea has put together the 'Problem Shared' campaign for there to be access to a qualified counsellor in every secondary school in the UK.

She believes this could have saved Daniel's life.

She said: "It's easier for young people to speak to a counsellor or someone they don't know rather than a teacher.

"Teenagers may find it embarrassing to talk to people they know and I think there is a lot of embarrassment associated with talking about mental health.

"Children at that age that are taking exams at school are especially important, the pressure on them is massive and there are so many other pressures outside of exams, too.

"I think a counsellor in school may have saved Daniel's life. It would have helped."

Chelsea hopes the campaign will stop other families from suffering a similar tragedy.

She said: "I can't do anything about Daniel's death but I wouldn't want another child to go through it.

"He spoke to teachers there but because there wasn't a counsellor put in place it wasn't enough.

"Before the campaign I felt the family was alone, but more people are opening up about their children and it sounds like a lot more children are feeling like Daniel did.

"It's so important. I wouldn't wish this on anyone else."

Chelsea presented a cheque of £10,000 fundraising to Martin House Children's Hospice last weekend.

The campaign has raised money through a number of events including raffles and a gala.

She added: "Martin House have been amazing. It upsets me because I wouldn't be doing any of this if Daniel was here, but it's amazing that we can do this because they deserve it so much.

"They've been there through everything."

The next aim for the fundraising duo is to raise enough money to purchase a 'cuddle blanket' for the Leeds General Infirmary where Daniel sadly passed away.

The blankets - which cost £5000 each - enable parents and families to spend more valuable time with their loved one once they have passed.
