What is 'paralysis of will'?

It is the phenomenon experienced by those with ADD in which, when dealing with sudden stressful situations or confrontation, or while attempting to make important or nonimportant decisions, the brain seems to cease to function, and the person is literally mentally paralyzed for a short period of time, usually until the situation is resolved or the conflict/confrontation has ended. This is often followed by periods of extreme self analysis and guilt.
