What a first appointment is actually like

Nobody makes you do anything in the first meeting. Somebody asks what has been happening, for how long, and what you have stopped doing because of it. It takes about an hour and most of it is you talking.

You do not have to repeat the thought. You can say that there is an intrusive thought with religious content that you find repugnant, and that will be enough. A clinician who works with this will not need the words and will not push for them.

Two terms are worth using, because they route you to the right person. Intrusive, and repetitive. If you say the doubt is intrusive and the responding is repetitive, most services will know where to send you.

Ask your doctor for a referral, or look for a therapist who names obsessive compulsive disorder rather than talking therapy in general. A good one will tell you themselves if they are not the right person.
