My 27 years old sister is schizophrenia patient. She is under homeopathy treatment. She has developed split personality. One is good and another is extremely bad. Bad personality abuses people, some time she attacks people with knife, she fights like anything and the good personality has that conscious mind that she is doing wrong things. She has the hallucinations where she can see someone is commanding her to do nasty things. Some time she becomes so violent that we are unable to handle her. Till at the age of 11-12 she was normal. After that she stopped communicating with world. Sometime she is very depressive and wanted to commit suicide. We are unable to understand how to deal with it and what are the treatments.
