I had a cousin who was Bi polar...I say "had" because his parents where out of town when he ran out of meds and he had shot himself time they got back.
It's not something to be "offended" about anymore than someone haveing any other disease is, it can be treated.

Depression can be like that as well though sometimes that can be caused by a dietary imbalance.

Either way, the person should get it checked.
