Do you use cannabis? If so discontinue use; it can exacerbate psychosis.
Are you on an AP? If not, try to get Latuda/Lurasidone, it works wonders for me and does not sedate you or make you gain weight.
Are you on a mood stabilizer? If not, try Lithium, it will balance out intracellular processes and help promote the growth of existing neural cells instead of potentially signalling for their destruction.
Do you take any additional amino acid supplements? If not, try N-MethylGlycine, Taurine, but not just glycine it will not get to CNS that way. Just trying to help! I was debilitated for 5 entire years, had voices telling me i was going to burn in Hell for 10,000 years ever single day but then i stopped smoking cannabis, got on the right medications, and began to write things down in a journal to take away the “fuel” for the thoughts and eventually the thoughts would wear down and not intrude in my life so much.
Hope this helps! Good luck!
