I've brought parents and a sibling to counseling. They didn't get it. And, with their POV on how life works and how I'm suppose to be they ciudad never get it. What the drag-alongs were good for were they really helped my therapist see what I was up against, both in my past and present. I do recommend bringing family members in, sparingly. But, if you expects the family member to come away with understanding of your situation you may come away disappointed, but if they are astute enough to get it, you will be one of the lucky ones.
