A.) I think those are "home" diagnoses. I think that LKH's kid, sister, and granny didn't or don't fall in with what LKH expects of them. Plus, it's a hot diagnosis at the moment. The chances of every woman in a given family having the same illness, especially when one's 'adopted', must be tiny. Regardless of the authenticity of the diagnosis, I sincerely hope that this post doesn't affect her kid's life.

C.) I think she's already made that hideously offensive post. I think it happened back when she was claiming to have Asperger's.
