How do I tell my therapist that I have OCD? I am a diagnosed bipolar but I have am also convinced that I have OCD. Should I just write down the symptoms that I have as I can truly relate to what all of you have been through, except for the fear of symmetry or HOCD. I have the fear that someone is cheating, even within my family. I do have a fixation with infidelity and sexuality and the OCD exaggerates it. I wonder about the percentages, the number of people that are cheating, the number of partners they have. I don't have any fears for myself. But with me the OCD takes apart of my personality and my issues and gives it a strange attachment that has nothing to do with my real life or the real life of my family's. Sometimes I do wonder if there is infidelity in my own family or if my father is my real father, despite the fact that I look like my dad. Sometimes I wonder if my brother is really my brother since he looks a lot less like my father than I do. It is crazy since mom has never cheated on my father and vice versa.
