Yeah, that is kinda why I don't wanna have kids. My mood swings and severe depression can't be good for a child. Bi-polar is hard, both for the individual, and the ones around him or her. I've lost so many girls cuz of my bi-polar. My last girl, who I'm still in love with (my pops was bi-polar and did not get diagnosed until i was in my late teens / early 20's.
i am convinced that seeing his wild mood swings made me suppress my emotions.
i don't let myself get to happy, sad, angry or excited...this was a point of contention between me and my girl for many years.
when we had an argument, i would never get furious.
when something good happened, i would not jump up and down.
i didn't want to let my emotions control me so i put them in a box and kept it moving.
my mom wanted me to see a shrink because she was concerned about me never being angry....i dunno...people are weird.

I'm pretty stable now with the myriad of drugs they got me on, but sometimes I get into a manic or depressed state. I can hide it at work (most of the time), but I can't hide it from a girlfriend.
