Last month, Holly revealed she would be releasing her own tell-all book Not Quite A Geordie, following her from a young school girl to the lovable reality star she is today.
Known for being on Geordie Shore, party girl Holly definitely doesn't come across as shy and insecure, but inside her autobiography the 22-year-old sadly tells a different story.
Reflecting on her teenage years in an excerpt published by the Mail Online, Holly reveals that she was constantly taunted about her looks and weight at school, so much so that the star, at one point, was driven to self harm.
She writes: "I stared at my image for an unusually long time, taking in all my features one by one and trying to understand why everyone thought I was so ugly... It made me so mad and I had no one but myself to take it out on."
Looking back at her time at school, Holly said she remembered the first time she was picked on after wearing the same skirt as another girl at a school disco, but "three times bigger" in size.
After being taunted then, Holly said the "comments made stuck with her" and from then on she started comparing herself to her friends and the way they looked - triggering her body and weight insecurities.
Holly claims that the bullying soon turned from taunts to physical violence as she was attacked at school by three other girls.
"They pushed my face... And you know what made it all worse? Practically the whole school was watching this mindless violence and not one person tried to break it up."
After enduring a tough time growing up, Holly is now a far cry from her former self.
As well as shedding light on her childhood in her new book, Holly delves into what really goes on behind-the-scenes on the hit MTV reality series and how she coped with becoming famous at just 18-years-old.
Not Quite A Geordie by Holly Hagan is available to pre-order from Amazon or iTunes. Available nationwide in store at WHSmith from October 2.
