hello,
You are having movement disorders, a side effect common with older and sometimes with newer antipsychotics. You should, meet your doctor, request him to look into these side effects. The doctor would either reduce the number of drugs, or may be take out the offending agent/ or atleast reduce the dosage of the offending agent. There are some meds which can be given to reduce these side effects, (these movement problems are commonly known as - extra pyramidal side effects).
So, it is not due to psychiatric diagnosis but due to the drugs which are given to you. Antidepressants generally don't cause these movement disorders ( jerky or tremors).
this should be looked into at the earliest, as they increase with time if the offending agent is not removed.
Also, the illness is relapsing in the form of increase in hearing of voices. Your doctor will have to increase the dosage of anti psychotics, preffrably newer ones (
olanzapine, or amisulpride or quiteapine) or may be shift you on some depot antipsychotics ( newer ones).
Wish you good health and speedy recovery
