Post-traumatic stress disorder (PTSD)

Post-traumatic stress disorder (PTSD) is an anxiety disorder that can develop in the aftermath of any traumatic event. A traumatic event is one in which we can see that we are in danger or witness other people dying or being injured; however, even hearing about the unexpected death or injury of a close friend or family member can result in PTSD. The symptoms of PTSD include r e-experiencing which can manifest as flashbacks or nightmares, and it can be so realistic that you feel as if you are reliving the traumatic experience. Avoidance is another symptom which happens when reliving the experience is too upsetting, so you distract yourself by avoiding anything, anyone, or anywhere that reminds you of the trauma. Another symptom is hypervigilance (being on guard) in which you cannot relax and are constantly alert and looking for danger.
