According to statistics from ChildHelp, around 6 million children in the US are abused each year, with around 3 million reports of abuse. 30% of adults who were abused as children often go on to abuse their own children. Child abuse can have long-lasting mental health consequences for victims, including anxiety, depression, and PTSD. Factors that may contribute to abuse include substance abuse, unrealistic expectations of children, lack of parenting skills, history of being abused, mental illness, and work pressures. Children who are abused often feel serious, unhappy, shy, depressed, and that they cannot rely on anyone for support.
