My dad is bipolar and schizophrenic, what are the odds that i will also get these diseases?

Low: Your dad can not have both, they are mutually exclusive illnesses; sometimes people get told different diagnoses over time. A child with a parent with schizophrenia has about a 13% chance of developing the illness in his or her lifetime. The risk of bipolar in a child with a parent with bipolar illness is about the same.

More info: True odds depend upon which of these diagnoses is correct--though there's also a chance that a mixed diagnostic picture means "schizoaffective disorder". Much also depends on the rest of the family tree, your age, and a careful review of your own history. Unfortunately, the statistical risks are at best approximate today--it's an active field of research. You might want to consult a pro in person.

If you are experiencing any symptoms causing you concern first please have a complete physical examination to know if you have an illness. If not, your medication should be managed by a Psychiatrist. If you are not confident in your Doctor please see another for a second opinion. Please see a Clinical Psychologist with expertise in multiple types of psychotherapy to help.
