I went manic on antidepressants but, that isn't why I was diagnosed bipolar, in fact, the psychiatrist who did the most recent diagnosis (yea, I've been diagnosed multiple times with this, long story) made a point to ensure that I had had manic episodes without antidepressants.

So what if doctors think people with the bipolar diagnosis must take medication? Unless you've done something that removes your rights, you have rights to refuse meds and you can even drop those doctors and start fresh with new ones who don't know your history (though could very well lead to the same conclusion but, still...you are not required to take drugs).
