Not all childhood trauma is from the family of origin or bullying. Sometimes life traumatizes us. I was put in the hospital when I was 4 for 6 months. To keep me from getting out of the hospital bed they put me in a cage. I cried my heart our every day especially when my mother left. I still have nightmares about this.
As a result I have an attachment disorder but no one is to blame.
