It is so often emphasized in media portrayals of schizophrenics. But voices and delusions can be of other types. A person can hear voices that are telling them how wonderful they are or a person can hear voices that are telling jokes. Similarly, delusions or false beliefs can be of other types, as well. But the paranoid type is the most common and the type that is most associated with the disorder of schizophrenia.
Paranoid schizophrenia is considered a sub-type of schizophrenia.
There is another whole category of symptoms in schizophrenia that are important to describe. And by negative symptoms we do not mean symptoms that are bad, or of negative value. What we are describing by negative is the absence of behavior that usually occurs versus something like hallucinations which are the presence of something that does not occur. The symptoms of schizophrenia as you have described them sound terribly disabling. There are a portion of individuals who develop schizophrenia and whose symptoms remit or whose symptoms subside or significantly go away with treatment to the point that the individuals function well and they are productive.
