Brooke said the hardest thing she had faced was the death of her mother and grandmother.
'Mum and Nan dying when I was younger and having to grow up without any parents (was the hardest thing),' she told OK!.
After the tragic passing of her mother, who Brooke reveals committed suicide, the Perth local spent the rest of her childhood living in fear of drug feulled violence.
However, the youth worker is using her own experience to help others.
Speaking to SBS' Noongar Dandjoo program, Brooke said, 'I grew up in a country town in Carnarvon. I spent my childhood there up until I was about 11, when my mum unfortunately passed away - she committed suicide,' she told host Neil Coyne.
'That was a hard time, living in Carnarvon with my mum and nan, losing Mum, and then Nan actually passed away a month later.'
Brooke reveals she eventually went to live with her father, but admitted 'he wasn't very supportive.'
'Growing up was pretty complicated. [There was] a lot of drug and alcohol violence in my childhood and I had an older sister who suffered from schizophrenia,' she said.
The reality TV star somehow found the strength to push through her own mental health issues to become a role model for her siblings.
Her brother Troy told the program: 'Brooke was definitely someone I had to run to when I had problems.
'I went through quite a bit of depression when I was on drugs, drinking a lot, wasn't really in the right place.'
Currently, Brooke is a favourite to win The Bachelor.
