I used to have a similar problem. I thought I would worship the devil without wanting to. I heard something about the Lord's prayer being said backwards and it was all I could do to lie in bed everynight and not find myself doing it. My lucky number was six and I became really scared of it, and myself. I wouldn't look in the mirror in the dark because I'd heard something about that too. One night the alarm clock was broken and it went to default 8:88 but a part was missing so it read 6:66 glowing red. I was so sure I'd be taken against my will, become a satanist. So you're not alone. I now have a good relationship with the creative power, and while some days I openly curse him, this is one OCD I have managed to put to rest. I believe God knows what's in your heart and on your mind, and if any part of you does believe in a God, believe too that He knows what you're going through. And if it makes you feel any better, I even got up the courage to look up satanism once and it's quite harmless. Lost souls, not forsaken ones and hedonists - people who believe they should please themself before others. All the other bad stuff is mostly just for film and TV and a few select people who would be evil no matter what.
Maybe try a novena. I use the Lord's Prayer and say it three times, three days in a row the moment I wake up and I try to understand every word and really mean it. I thank him for all that he has given me and ask humbly if he will please... through the sacred heart of Jesus, and within three days, weeks or months, it's mine. Hope this helps.

Hello there

YOur OK dont forget your mind is a like a computer that generates all kinds of images, thoughts, ideas, impulses its part of being human the difference with OCD is that we take everything at face value..ANXIETY will drive your mind to think the craziest things ever!! Anxiety can cause you to create all kinds of ideas and images!! I know this to be true!! THere is an old saying " what we fear we create" this does NOT mean that you are creating Schzophrenia in yourself it means that your mind is trying to force you to face your fears so you can move passed this!! our minds and bodies do take care of themselves sometimes we just have to listen...You are just caught in the idea...you are ok..I feel your pain I really do!! Hang in there...try to stay busy....another thing that helps me is to just sit or lay in a quiet place and tell myself "OK go crazy " go as crazy and you want" and you will be surprised at what happens...at first you will be scared to death and creating all kinds of crazy thoughts images and then you will come down and bit and suddenly you'll realize that this is just creativty at work...It has worked for me but, you have to be brave enough to face it..sometimes just saying hey if I am schizophrenic then I will deal with it and I will be OK..letting go can make you stronger! remember your brain is a creative computer and thats all thats at work here!! also schizophrenic people are not on OCD help sites asking for reassurance because they are afraid they have lost or are losing their minds!! take care of you!!

Doesn't sound like schizophrenia. Sounds like a classic case of OCD. I get images of me stabbing myself or stabbing the person that I am talking to and they are bloody. I'm not violent at all and find these images disturbing. I can understand your distress as these images are scarey. Sometimes when i am on the bus, I get images of the bus crashing and everyone dieing.
Like I said...you aren't losing your mind. THe images are driven by fear and your brain is trying to beat the fear if that makes any sense.

Do you abuse any substances or have you in the past? Having a few glasses of wine everynight is substance abuse.
