My grandfather was manic depressive before term bipolar was used. My uncle is most likely bipolar always had the habit of taking off at times without a word, suffers depressions, makes the worst financial descions and is a genius who refuses to accept promotions at work he says because of stress involved with predicting uncontrollable variables or management of countless idiots. Also have several cousins i am aware of with previous depressive episodes whether they have turned out to be more i am un aware of.
