I had read that she was not able to continue to offer sessions due to a medical condition. I'm sorry I never got a chance to meet her, but Houston has never been on my list if places to visit.
From her sessiongirls page:
"In response to unkind remarks made insufficient of context, I feel compelled to disclose I am unable to session due to medical reasons. Furthermore, my current health has required the indefinite postponement of any session outstanding."
