Visual helusunation. Medical advice.

My wife, 26F, developed severe depression, anger and shouting after her younger brother’s death. A few days later, she started having visual hallucinations (frightening man, child, woman etc.), auditory hallucinations and sometimes felt that the figures were touching her. We consulted a government psychiatrist who prescribed Olanzapine, Clonazepam, Amisulpride, Trihexyphenidyl Hydrochloride and Fludac (Fluoxetine). She has taken them for 2 months and improved significantly. Visual hallucinations have stopped, but occasional voices and confusion remain. Her psychiatrist has now been transferred and there is no psychiatrist at that hospital. Private treatment is unaffordable. Please advise whether she should continue the same medicines/doses, whether any change is needed, and whether a 30-day prescription is appropriate. We will not change or stop medicines without medical advice.
