The best move you can make is to see your school counselor now.  And if you don't get the attention you need there, then see a psychiatrist.   As Christina said, there are plenty of reasons for these symptoms, one of the major reasons being stress.  Stress of being a teen, of having to "perform" well for school, the news of your dad's having schizophrenia, and whatever other stresses are going on in your life.  You might also look into participating in a class on meditation or yoga which are often available at local community centers.  Whether you have schizophrenia or not, moderating your reaction to stress is always a good thing.   Best wishes,   Carolyn   P.S.  Please report back to us after seeing your school counselor.  This is a good site for support.
