OCD, though indisputably a disease, is a disease that afflicts the will itself. It is an affliction of the will. A person with osteoporosis is somebody with porous bones, not a porous will. A person with cancer is somebody with damaged cells, not with a damaged will. But somebody with OCD is somebody with a damaged will. And the only way to fix a damaged will is by exercising that will. And that is what the obsessive-compulsive must do. And if he doesn’t do that, he is quite as responsible for his condition as is a fat person who refuses to stop overeating.
