well, if its just lately, did some circumstance change? did something get added/lost or some lifestyle change make you feel this way?
or if its been going on for a while, say, months into years, start troubleshooting. alcohol/drug use, porn consumption, exercise or lack thereof, media consumption, DIET (diet is huge), any of these things could make you feel worse without realizing. could be something as easy as a food or alcohol sensitivity.
equally important though it sounds like you have no one to relate to IRL. you certainly aren't alone and more people feel that way than would admit. try adult sports? or skiing? fishing??? art class? metal detecting?? volunteer at the library? animal shelter?? Bible study??????? there's gotta be somewhere some group of people will accept you in person even if its only on one or 2 levels and you keep the nigger and jew discussions to Poal.
sorry that you are feeling like that. if you were serious about feeling schizo, real schizophrenia is a motherfucker. not much to treat that but antipsychotic drugs all of which have a terrible side effect profile. i would try doing what @IndoAryan suggested first, then find somewhere i could go like once a week to do some activity with other people for a few hours.
