If her current pscychiatrist is not well informed enough than try a different one. We sometimes try different pscychiatrist too.
I wish I could help your sister. We can't ask the pscychiatrist here in the states about someone else because they need to see that person to make any evaluations. Your sister needs a pscychiatrist, they can help her. Do your research on the Internet and bring it into the dr. Pscychiatrist know more about mental illness than just a general dr. I do understand your frustration and you care so deeply for your sister and getting her the right help. See if you can find a pscychiatrist even if it is far from where you live in your village.
That would be best for your sister. Take care.
