Post-traumatic stress disorder (PTSD)

Post-traumatic stress disorder, or PTSD, is a strong and lasting emotional reaction to a very disturbing event, such as war, violent crime, or a natural disaster.

It's normal for such events to make you feel scared, confused, or angry for a while. But if these feelings don't go away or if they get worse, you may have PTSD. Symptoms include having nightmares or flashbacks about the event, not being able to feel or express emotions toward loved ones, and being easily angered or "on edge."

PTSD can make it very hard for you to deal with life, your job, or your family and friends. Treatment with counseling and medicines can help.
