Since the cause is at best unclear, it's difficult for any honest practitioner to offer a cure. You might find unscrupulous individuals who make such claims, but please avoid them. It's been said many times already, but is important enough to bear repeating: the purpose of therapy is to help you learn to live more effectively. If you express the concern that CDing is hurtful, your practitioner MAY be able to help you find coping mechanisms that if practiced diligently allow you to push your thoughts of CDing out of your mind at least momentarily.
I think it needs also to be said that therapy isn't a three and out endeavor. By the third session you may have determined if the therapist is a good fit for you, but the real work takes months, not a few days. Don't expect to feel different after three sessions or five or ten. Think instead of the sessions as classroom work...instruction...to be followed by a lot of homework.
