Trauma is the mind and body's response to an experience that was terrifying, painful or beyond what you could cope with, such as violence, an accident, war, detention, abuse or forced migration. Sometimes trauma comes from repeated hard experiences in childhood.
After trauma, memories may return uninvited, you may have nightmares, feel constantly on guard or avoid anything that reminds you of what happened. When these symptoms persist, this is sometimes called post-traumatic stress disorder (PTSD). These reactions are not a sign of weakness, and with the right help the mind can hold these experiences more calmly.
