Can benzos overdose trigger aggression?

29. Male. 5'6". 74 kg. Currently taking paliperidone 150 mg monthly depot. I overdosed on etizolam last year. Doctor had prescribed it as SOS medicine. I thought taking all the pills might cure my condition as I had felt better last time I took a newly prescribed medication. So long story short I was hospitalized after the overdose. My doctor says during my hospitalization my dopamine shot up as I had gotten aggressive. He put me on paliperidone 75 mg depot on which I am still on to this day. My question was should a medicine be started for life when symptoms have been present in as acute situation as an overdose. Shouldnt things like paradoxical reaction or dopamine shoot after acute overdose should be considered before diagnosing me with positive symptoms of schizophrenia?
