I have a hysteria disorder but last year I started to totally forget things that happened, including talking to a police officer after a fender bender. They totally help me to really melt from hysteria but if a take any more than for maybe sleep, I forget whole conversations. Why is that? I have also taken ten Xanax and slept for a whole day and night. Did I overdose to the point I may die? I really suffer and go into hysterics during stress and they help usually.
