I know this is a dead topic but to adorable – I don’t know about this woman you heard about but when the OCD behavior is about religious things (as it is with me, according to the opinions that I have it in the first place) there tends to be a good deal of rationality involved. Sometimes all it takes is pointing to the right place in the shulchan aruch and the behavior stops. Other times the person might need a special heter custom-made for them. Maybe by non-religious stuff its also rational – I wouldn’t know.
TikunHatzot – The way I see it is that all treatments are annoying. They are expensive, and they either play around with your brain or take a significant time commitment. Some may have side effects too. So since they’re annoying, they should only be taken when the O and C become even more annoying than the alternative. Or if you feel a religious obligation to go on treatment, which is often related to how disturbing the O and C is. My take on things.
