Wow. That's a real heart breaker Gary. It's obvious you love your sister very much and she is lucky to have that in her life.

Does she have lucid times, times when you can talk frankly about the baby idea for instance, when she can acknowledge that it isn't so? I guess I'm thinking that you really want to watch for any surfacing of her real self, as it were, and reach out most at those times. Unless and until she can connect with an idea of herself helping herself, you are likely not to see much change.

You mentioned some bilingual ability of your own as to the language of psychosis. Not meaning to pry or anything, but am I right in thinking your sister is not the only person in your family with a mi? My grandmother, mother, brother and sister all have either bipolar, chronic depression, borderline personality and psychotic features. Some of the most effective meds for the worst states ended up being the same for all of us. So, if you have some med experience, it could be informative to her doc to know about it. Your parents? Either of them suffer from mi? Any meds? In my experience and my siblings' and my mother's no doctor ever inquired about any other family member's meds.

I wish I could come up with something useful for you, even a jumping off place would be good, huh? You love your sister, and tuning into that is probably your best course. Try to be alert in new ways. I get the feeling it will "turn" to whatever degree it might because of "contact" from you.

Despite her confusion, will she "engage" about anything at all? Will she answer questions and converse about this baby/pregnancy idea? Is there something like that you can gain trust with?

I don't suppose brainstorming out loud here is really helping you, but its a gut wrenching story you've shared. I'm always around if you want to keep talking about it. Probably a good idea.

You're a good person Gary, with a good heart. Take care of yourself too, K?
