My boyfriend has been diagnosed with Schizophrenia for about 9 years now, he was taking medication when he was 17 (he's 25 now) and he stopped taking them when symptoms got mild. Now, under stress and lack of sleep, symptoms can appear again. He has been paranoid about a few things, and when we talked he said he didn't want to take any medications. Especially anxiety medications because it made him lazy and unactive. He's afraid of seeking help because he doesn't want to be hospitalized. Now my question: Can it get worse than just a few paranoid feelings? Can it be violent?
