V - I would second that the family seek out some counselling. When I run into these types of problems with patients (for eg, a lot of their issues are psychological and a few are physical and the psych ones are interfering...) I usually explain clearly what it is that I am good at and explain that the current issue is something that I cannot address with my bag of tricks. Then I explain that the next step is to direct them to someone who can help them with the issue at hand and I reiterate that that person is not me.
That sucks. I can't wait to read your bike fit post and I do hope that it's happy.
