Welcome to PC ali! Sorry to hear you suffer with that disorder. I don't know if something like this would help you... but I use a CD (it's a mix of what you might think of as futuristic starwars melodies) designed to take the brain into delta wave. I use it to help me calm, and fall asleep.

I don't have schizophrenia, but I do have terrible reactions to all the antidepressants, so I understand that frustration! TC
