Abnormal psychology

Abnormal psychology is the study of what happens when things don't always go the way we think they should. It's the study of why people may act in different ways than we would expect such as being really sad for a long time, feeling scared all the time, or hurting themselves on purpose. People who do these kinds of things may need help from professionals to figure out why they behave this way and to get them back to feeling better.
