Content warning: This article discusses child abuse and trauma.
It's only once people have grown up that they reflect on their childhood and how it shaped who they are today.
For some, this will bring up happy memories from a love-filled home and for others it can shine a light on some very painful trauma.
In a online forum, people bravely shared their stories about the exact moment they realised their parents were bad at parenting and the stories are truly heartbreaking.

"Probably when I was 11. I came home from school and couldn't enter the house because all the doors were locked. I knocked loudly and could get no response. My female parents' car (some people call them mothers) was there, so I knew she was home. Finally, after about 45 minutes, she opened the front door and coldly asked me what I wanted. I was confused but responded that I was home from school. I'll never ever forget her response and how it affected my entire life forward: 'You don't live here anymore, your clothes are boxed and in the garage'."
"When I was about 14, I realised my mum's method of child rearing was toxic and abnormal. It just struck me as she stomped up the stairs she was having a sort of tantrum. She would hit us, rage at us, followed by days of the silent treatment. My Dad would be nowhere to be seen. My sister and I were supposed to be copies of our mother, extensions of her. She had a rigid way of doing things and we were her soldiers. I almost didn't pass nursing school because I was afraid to make decisions on my own for fear of making a mistake."
