Panic Attacks: The person may fear that they are going crazy, are out of control or that they are about to die. There can be a sense of unrealness – this may be a form of disassociation called depersonalization. The sense that everything around you feels unreal may be derealization. Panic attacks will NOT lead to death. Please see medical evaluation for this.
