You know them. I know them. And, increasingly, psychiatrists know them. People who feel they have been wronged by someone and are so bitter they can barely function other than to ruminate about their circumstances.

This behavior is so common -- and so deeply destructive -- that some psychiatrists are urging it be identified as a mental illness under the name post-traumatic embitterment disorder. The behavior was discussed before an enthusiastic audience last week at a meeting of the American Psychiatric Assn. in San Francisco.

The disorder is modeled after post-traumatic stress disorder because it too is a response to a trauma that endures. People with PTSD are left fearful and anxious. Embittered people are left seething for revenge.

"They feel the world has treated them unfairly. It's one step more complex than anger. They're angry plus helpless," says Dr. Michael Linden, a German psychiatrist who named the behavior.
