the reason why i dont want to pass it down is beacause medications every day your a slave to it they make you drowsy shake and have really awful side effects its not a miricle pill i told my doctor to shove it when he put me on risperdale and other medications because of medications i lost an entire year of my life to be a "xanie zombie" so to speak medications are emotion blockers i wont have my child on them expetially because most of the medications are so addicting and no i dont believe in marrage we have been togeather years now we both dont believe in marrage...its just a money waist

Manic depressive disorder and bipolar, aren't those the same thing? I would say if you both have the same disorder chances of passing it would definitely be great.
