When terrorist-controlled airliners destroyed the World Trade Center's twin towers and crashed into the Pentagon, they not only shattered the lives of thousands of people directly in the line of fire. They also attacked America's psyche. Today, people from sea to shining sea are still dealing with the emotional repercussions of the events of Sept.11, 2001.

As with the assassination of President Kennedy, nearly all Americans will forever recall where they were when the jets slammed into the towers, and how they sat transfixed, watching the horrific televised images of the unprecedented carnage. But long after the disturbing news reports faded from TV screens, some Americans are still searching for a return to psychological balance.

According to mental health experts, many men and women have shown an amazing resilience since 9/11, often buoyed by feelings of patriotism and national pride, sometimes by just the passage of time. Although national surveys reported common problems like sleeping difficulties, trouble concentrating, and feelings of vulnerability in the weeks and months after the attacks, those symptoms have gradually subsided in many individuals. Others, however, still remain anxious and fearful as they continue to cope with the lingering psychological effects of the terrorist attacks -- whether they live near Ground Zero or thousands of miles away.
