To preface this, I do not have bipolar disorder, although I am considered nuerodivergent/metally ill. So take what I say with a grain of salt.

I suggest doing a lot of research about the disease. Bipolar disorder, also know as Manic Depressive Disorder, is really complex, but to simplify it, it's characterized by periods of excessive emotions that switch with little to no warning. I think one BIG mistake people make with bipolar disorder is the idea that people switch emotions every other second. Most often this is not the case, and most bipolar people switch between Manic, or highly energized, and Depressive states. These states can last days, weeks, or even months, but will always be very different from the person's "normal" behaviors.
