Schizophrenia. Please explain what i do?

In college days I used to smoke, drink alcohol, smoke ganja, weed. After lockdown I remained packed at my home and I was hit by schizophrenia in lockdown(2020), I was unable to sleep, bath, eat properly, speak, walk also I used to walk at midnight having my eyes closed(neend me chalna in Hindi), I felt like my legs were raising automatically above the ceiling in midnight and many more. I thought people were here to kill me on this planet. It was also like I was having some spiritual powers within me. Sometimes I had lots of confidence and sometimes very low confidence. My parents also did (jhaad phook), called Babas in house so that I can be cured, The situation became the worst day by day. After some local doctors suggested taking an appointment with a neurologist, till now I am on medication {neurlin(1tab) in the morning}, {escita plus(1tab), mortab20(2tab), risdrome LS(1.5tab) in night}. How long will the medication last? Will this disease come again? Please explain what I do?
