Schizophrenia is a severe mental illness that can affect your ability to think clearly, manage your emotions, and interact with others. Most people who have it hear or see things that aren't there (hallucinations), believe things that aren't true (delusions), or think someone is trying to harm them (paranoia).
Schizophrenia is not the same as a "split personality" (dissociative identity disorder).
