What is the effect of psychosis medication on people with depression? Is normal therapy better or is medication necessary?

I am unsure as to what motivated you to post this question and frankly it does concern me. 

Whether you (or someone you are concerned about) require help or are simply curious please seek professional medical advice. 

Anyone else reading this; refrain from answering unless you are a trained mental specialist i.e. a psychiatrist. 

Psychological stress just need Psychotherapy
