I was diagnosed with bipolar but i don't remember experiencing mania. i don't want to take unnecessary meds. how can i bring this up with my doctor?

Good question: Tell your doctor you want to understand what bipolar diagnosis means as it applies to you. Ask your parents or other family to tell you how you acted when this diagnosis was made. Important to have this open discussion. Ask if your diagnosis could have been something else. Great to question your diagnosis to better understand yourself.
