The trauma and shock of early childhood abuse often affects how well the survivor learns to control his or her emotions. Problems in this area lead to frequent outbursts of extreme emotions, including anger and rage.

How Can Anger After a Trauma Become a Problem?

In people with PTSD, their response to extreme threat can become "stuck." This may lead to responding to all stress in survival mode. If you have PTSD, you may be more likely to react to any stress with "full activation." You may react as if your life or self were threatened.

This automatic response of irritability and anger in those with PTSD can create serious problems in the workplace and in family life. It can also affect your feelings about yourself and your role in society.
