Post-traumatic stress disorder (PTSD) is a mental health condition that can result from going through stressful, upsetting, and scary experiences. People with PTSD may develop complex PTSD or CPTSD if the traumatic experiences were recurrent, protracted, or complicated. It can happen during a period of natural tragedy, war, or physical or sexual assault. Intrusive memories, melancholy, anxiety, feelings of detachment, trouble controlling emotions and sustaining relationships, and changes in one’s self-perception are just a few of the symptoms that can result from CPTSD.
