I wish i could help you here love but i'm not too sure of what the answer may be. perhaps if you ask this at the Ask doctor Question posts you may get the answer you're looking for.

Antipsychotics are not used for just any disorder. What I get from what you wrote is that your doctor thinks you have depression with a schizo affective presentation. Antipsychotics would help with some of the hallucinations and delusions that are associated with a schizo affective presentation.

Treatment of any mental disorder is not an exact science. There is no "one size fits all" treatment. Everyone is unique and will respond differently to medications. This is true of any class of medication. Some people need to try several antihypertensive medications before they get their high blood pressure under control. This holds true with any neuroleptics. Unfortunately, it is through trial and error that doctors will find the right combination of medication to treat mental illness. There is science behind the medications but individual response is impossible to predict.

Trust in your doctor is important. Have you consulted with another psychiatrist? Getting confirmation of a diagnosis is helpful to many people. It is possible that another psychiatrist would not agree with the diagnosis. Finding a doctor you can trust to treat you is so important.
