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. Common causes of abuse include substance abuse, unrealistic expectations of the child, lack of parenting skills, being abused oneself as a child, mental illness, and work pressures. Children who are abused may become shy, unhappy, and feel they cannot rely on or trust others.
