Sounds like your OCD centers around religious obsessions and rituals. A cognitive-behavioral therapist can really help you with these types of obsessions, as OCD is a very treatable disease.
Yes, ocd is hell, but you would be amazed at how much help you get from a trained professional to help get your thinking back on track...ocd is a special way of handling anxiety, and if you can pierce the cloud and deal with anxiety, the ocd goes away.
