schizphrenia has been linked to a cat parasite called toxoplasmosis. you might want to try a few round of humaworm or another quality anti parasite product. here is some info, you can get more by googling 'schizophrenia + parasite + cat'
by the way how old are you? a good friend of mine was diagnosed with schizophrenia and it was the worst during his 20 and 30's. he is now 46 and he says he doesn't really feel like he has any symptoms at all and takes no medication. of course everyone is different.
