No. The idea that bipolar disorder is "biological" doesn't comfort me or even alleviate any responsibility or stigma in my mind.

When I was younger I had a room mate who admited she was jealous of my bipolar diagnosis. Not because of what I would go through but because it made me interesting also some idiot childhood friend of hehad thought he had it too and felt "closer" to me than her because of it. She actually admitted these things too me then went and pretended to be bipolar for about 3 days. I'm not sure why, it clearly got exhausting for her especially when nobody gave a damn.
