A psychologist for the Worthington Center says some people are still suffering post-traumatic stress disorder, nearly a year after the attacks on New York and Washington, D.C.
Psychologist Bill Hale says the key to coping with it, is not to place too much emphasis on it.
"I don't think there's anyone in this country who didn't know what happened that day," says Hale.
Similarly tragic events in our nation's history have had enough of an impact, that people remember where they were when they first heard about them. That's particularly true since the beginnings of electronic communication.
"As far as people re-living it," Hale says, "I think they should not try to make things harder than what they already are. They're already going to be bad enough."
Hale says first-year anniversaries of major tragedies can be difficult, and that people shouldn't be embarrassed to grieve.
He says at the same time, however, people should occupy themselves with other activities, and not spend too much time reflecting on the tragedy.
