Someone with schizophrenia
Sometimes the voices are friendly however, most
often they are cruel and taunting. Hearing
voices for the first time was very scary to me. I
call my voices "superiors" they are of demonic
nature and continuously telling me "I'm evil and
worthless". They often command me to hurt myself.
I do as they say because they threaten to kill me
or bury me alive their terror controls my
behavior. I also have visual
hallucinations in which I see things that
apparently no one else sees. I
look at people's faces and they suddenly
disintegrate or are so distorted that they appear
in horrifying form, wicked,and I see the evilness
of the devil locked within their eyes. I may look
at you and project someone's else's picture on
your face everything becomes confusing and quite
frustrating.
