After a traumatic experience, it's normal to feel frightened, sad, anxious, and disconnected. But if the upset doesn't fade and you feel stuck with a constant sense of danger and painful memories, you may be suffering from post-traumatic stress disorder (PTSD). It can seem like you'll never get over what happened or feel normal again. But by seeking treatment, reaching out for support, and developing new coping skills, you can overcome PTSD and move on with your life.
