Combitone Capsule

My sister was suffering from some kind of mental illness, she is hearing things. She thinks that she is good but 'someone' is trying to make her bad (spoil her) but she choose to be in the right path. But other people may listen to that 'someone' and start criticizing her. So, she is afraid. She keeps telling that her mind is divided into three parts-part1 is telling her to make herself educated, part-2 is telling her to control her body language and part 3 is that part which is telling her the things that someone has told her earlier to spoil her but she never allowed them to enter her mind. It started before four days (though she keeps saying things like some people are bad, she always had a doubtful kind of attitude but it became very serious now. Before three days from now, she became out of control, she suddenly starts crying and then laugh at the same time, she was behaving and acting like she was afraid of something. We took her to a consultant (Psychiatrist probably), he told that she is having extreme depression and prescribed medicines (*i don't know everything what he said because I was not allowed to enter the chamber, my father and mother went inside with her)*.That day she wasn't talking with us but from the next she started making some progress but she keeps telling the same things again and again. We are trying to help her and telling her to forget all those things but after sometimes she starts to tell the same things. Though she can read and write very well like normal (I asked her to make me understand a chapter of my book, she did it like she usually does). Medicines prescribed by doctor are: combitone plus oltha 7.5 tremnil zolford From yesterday she became a bit normal but she keeps asking us about the real sounds, if they are real or not. I want to know it is Schizophrenia, bipolar disorder or just depression? And will she ever become normal without any future trouble? PLEASE HELP!
