My mom was a marriage councilor. Her marriage and the subsequent divorce were out of this world bad. She pretty much managed to hit almost every stereotypical negative behavior trait.
In general, my experience with counseling, therapy, social workers et al. were that you might be better off spending the money on a rollecoaster ride. At least it's guaranteed to end.
Especially the social workers. I have an impression that their exams have an inverted grading scale: you need to score below a certain threshold to graduate.
