Lucami, I am so sorry you're going through this. It sounds like a living nightmare. I have bipolar disorder and generalized anxiety disorder. I was plagued with these kind of thoughts a few years ago. My therapist was very understanding, but that is horrible that your doctor would laugh when you told him this. I took a personality test, really long test with like 500 questions, and it was deemed "invalid" because I answered some questions yes, like do I ever feel possessed and even if I thought life might be easier as the opposite sex. I feel so much spiritual guilt that I think I was possessed at times and under the control of an evil spirit. My therapist says this sounds like dissociation. You might want to check out the dissociation forum. I know you're really scared and creeped out right now. Try to avoid things that are triggering you and maybe go to church and pray, if that helps at all. I find church to be a peaceful place when I get scared. Please keep us updated.
