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.
