I have done a research on that. Well, I'm not sure whether she is
really suffering from schizophrenia. She always tell me that she
has trembling hands since age 16. She thought it's normal, because
she was a premature baby, many organs not fully developed. And so
she din seek treatment. She has a weak heart too, and low blood
pressure. And as I read about schizophrenia, it says that it is a
brain abnormality, and heart disease could also be the cause of
it.
