Davey....you almost make it sound as if BP was/is contagious........
EVERYBODY is a product of their environment...good, bad, & the ugly.....If you add in the tendency for BP genetic predisposition...it sounds like you got the short end of the stick.........

AS for rhapsody, my dear, I would avoid contact with this person whenever possible....less stress on you....but I wouldn't make a big deal that this person is the reason......if he is feeding off the attention...positive or negative.... knowing this would give him power, at least in his mind.

Think of it like trying to teach a pig to sing ...all it does is frustrate you & annoy the pig
