| − | | Post-traumatic stress disorder (PTSD) is an anxiety disorder caused by very stressful, frightening or distressing events. Someone with PTSD often relives the traumatic event through nightmares and flashbacks, and may experience feelings of isolation, irritability and guilt. They may also have problems sleeping, such as insomnia, and find concentrating difficult. These symptoms are often severe and persistent enough to have a significant impact on the person's day-to-day life. Re-experiencing is the most typical symptom of PTSD. This is when a person involuntarily and vividly relives the traumatic event in the form of:

For example, they may wonder why the event happened to them and if they could have done anything to stop it, which can lead to feelings of guilt or shame.

This usually means avoiding certain people or places that remind you of the trauma, or avoiding talking to anyone about your experience. Many people with PTSD try to push memories of the event out of their mind, often distracting themselves with work or hobbies. Some people attempt to deal with their feelings by trying not to feel anything at all. This is known as emotional numbing. This can lead to the person becoming isolated and withdrawn, and they may also give up pursuing activities they used to enjoy.
