I suspect that many cases can be helped by religion, as many cases can be helped by other lifestyle changes. None of those are cures and none of them work for everyone, but that's alright because as far as I know, there are no known cures and the most reliable treatment is some sort of mood stabilizing medication--and none of them work for everyone either. If something works for the person who is writing the post, it could very well work for someone else which is why we have forums to share that sort of thing.
