Brief answer..yes, it is

Detailed Answer:

Hello,
I have gone through your query in detail and understand your concern regarding these drugs will work for depressive psychosis or not

Mirtazapine is a good antidepressant which also improves biological functions like sleep and appetite along with depressive symptoms

Quetiapine works better for psychosis, it also helps in sleep

Cymbalta works better for any somatic symptoms associated with depression

I think it's better to continue these drugs

Hope this information would help you
Thank you
Dr. Soujanya
