Exorcisms etc.

I think my patient needs an exorcism! I don't know how I feel about exorcisms, except that I have always been extremely disturbed by the thought. I have never watched the movie "The Exorcist" because I believe in good and evil. I believe in God and Satan. Therefore, movies with demonic possessions give me nightmares and create a hypervigilence in me to never accidentally allow myself to be possessed. I can't explain exactly why I believe my patient needs an exorcism. I can't put my finger on what is really wrong with her. I've diagnosed schizophrenia, but her symptoms are so bizarre and chilling. In her eyes I see a type of evil that can't be explained. Yet, I also see a terrified and tragic young girl who will cry the occasional tear. (not tears of blood thank God) Zyprexa or an exorcism? I really don't know.
