I do hate when you end up with doctors who clearly have no idea how to handle mental health problems. I've been quite lucky over the years but a couple of times I've had to just nod and leave quickly and find a way to see someone different next time. Yours does seen a bit like he'd not really dealt with someone with OCD before. Still, you'd think there would be better ways of getting information than asking your patient a billion questions... Pfft.
