Britain’s Got Talent star and chart topper Susan Boyle has revealed that her struggle with depression is linked to being bullied at school.

She spoke of the ‘absolute hell’ she suffered as a child that she believes lead to her recent problems.

SuBo told The Sun: “I can be up and down like a yo-yo. I can be depressed.

“I know I’m taking a big chance telling people this, but you have to be honest. I used to be made a fool of at school.

“It was psychological bullying and that leaves a scar and it also cultivates a lot of anger.

“When people are a wee bit slow others pick at them. My life was made absolute hell.”

Susan released her debut album I Dreamed a Dream last month and it has sold three million copies so far.

The Britain’s Got Talent star told an Australian TV show: “When I went on Britain’s Got Talent I said this is a chance to prove myself.

“I can be a bit funny after being tired, but whenever I go on stage I forget all about that.

“I feel I’ve got a communication with the audience. I’m told I’m a different person on stage.”

She also revealed that the death of her mum in 2007 has hit her hard: “In some ways I had a conflict with my mother – everyone argues.

“It makes me cry and I’m trying not to now. She’s not alive to see how proud I could have made her.”
