If a drug didn't make you feel/function better, you should give up that drug.
Sertraline is just one of multitude of antidepressants, maybe it's not the right one for you.
I firmly believe, instead of adding antipsychotics to sertraline, you should try different antidepressants until you find one that really helps you.
I'm currently on vortioxetine.
