Post Traumatic Stress Disorder (PTSD) is an anxiety disorder that can develop after you have experienced a traumatic event or a series of traumatic events.

Anyone who has been through such an event can develop PTSD.

After such events it is normal to feel distressed, frightened or angry. It is also not unusual to have symptoms of PTSD such as sleep disturbance and flashbacks.
