It is good to get out if it is not helping you or if you can't rearrange it in such a way to be useful, but some people do get a benefit out of it. I see no reason to not believe those who say they did benefit any more than I would not doubt those who say therapy failed them. I don't believe it is all or nothing - just as one type is not for everyone nor is therapy itself in any form for everyone. But just because it is not for everyone doesn't mean that it is not right or good for some people.
