What to do if you think you have both autism and bipolar disorder
If you suspect that you have bipolar disorder, you should see a psychiatrist. They will help determine if your symptom is because of an acute medical issue. After examining you and ruling out such a condition, they may refer you to another mental health specialist for a second opinion.
In this situation, consulting with a psychiatrist or other mental health experts is much more recommended than a general practitioner. Book an appointment with one of these specialists for reexamining. This will help find a diagnosis or a reason for the symptoms you are experiencing.
