It happened to my wife. She become so aggresive and so much tension, hallucination and delusion. After that, my wife gradually become muted and passive. Also, she unable to move properly. Refused to eat and shower. Just staying on the bed the whole day. It is already two month she in that condition.
I searched in the internet and found the symptom called catatonia (stupor).
I am happy that she gradually losse her anxiety and aggresiveness, but, seeing her in 'sloth' like person, make me feel worried.
Ps: sorry for my bad english...
