I don't know how common it is, but I do know there are women in the school who "think they're going to have Ramtha(TM)'s baby.
They actually fall in love with the persona, and I've seen JZasR kissing women on the lips as she as "he" entered the arena. Man, they were lining up, the belief is so strong, in fact, she as "R" said, "if you don't think I'm a man just ask one of these women."

I wish the best to your cousin.

I agree re the 'transference' syndrome of cult members onto the leader as a spouse or sex partner. This is a common, almost ridiculously repeated phenomenon---ever wonder why so many cult leaders [like rock stars] have sex with followers? It is an atavistic [herd animal] response of the primitive self to want to 'mate' with the strongest or most attractive, and the leader to percieve himself as "lead stallion" [or in case of female--"temple prostitute." Once a strong moral code is eroded by group ideology, or a leader establishes double standards ['I am enlightened, therefore I am entitled']this almost always happens in totalist cults.

The worst cases I've seen in mental hospitals is when a cult member patient believes that he or she is "the God".

If mania with psychosis is the diagnosis, the facility's docs probably administered or treated with Haldol/Cogentin or Risperdal, sometimes Geodon [more expensive]or Prolixin, depending on what the patient tolerates the best. Manic psychosis responds well to most of these. If she took a newer antidepressent at RSE [unprescribed]like Prozac, she may have had a reaction that looks like manic psychosis. Blood lab results will help the staff determine some of that.

Privacy laws will keep family from knowing too much but the patient can sign releases when she is ready or "sane" enough.

I wish you well, Kate. The advice above to give her support, as much as she will tolerate, is excellent. Hospitals tend to treat and release to out patient asap, and it takes social support to keep people involved with their treatment.

all the best to you and your cousin Kate.
It's a rough road, but your just being there will help tremendously.
