You don’t need to give up your children. I’ve known several OCD sufferers terrified of hurting people including their own families and they never did. Our sense of decency and revulsion at even the thought of hurting somone is what causes the terror as I well  know. Sometimes I think sufferers haven’t necessarily found the right therapist, aren’t in the right space mentally to engage or have other reasons why therapy isn’t helpful. That’s not me saying I don’t think it’s helpful as I believe therapy is – right therapy, right therapist and the right time I mean.
