Person suffering from extreme fear or anxiety, usually as part of their anxiety, personality, or psychotic disorders.
They do not move, not because they can't or because they are
lazy, but because of fear, embarrassment, bad feelings.
Most of social anxiety sufferers resume
normal moving, when they are alone. They only freeze when near
people.
Besides not moving, they have other symptoms such as headache, toothache, jaw pain, because these organs freeze too.
When guests arrived at my
house, my body started to
shake, sweat, and I could not move for few hours.
When they left, I resumed my
normal activities. Hell of a day! I think I am a catatonic.
