If it's what you want to do, go for it. A lot of people saying it's completely worthless, it's worthless for. Of course it's not going to be worth much for someone who has little interest in it and is studying something else, something they consider superior. Don't feel bad for not taking something vocational. If you want to go into psychology, take psychology. You can be taken down many different paths with psychology, so if you have nothing specific in mind that's fine! If you think you'll enjoy it and you like the sound of the course, then by all means go for it.
