I have both BP and some strong BPD tendencies.

So, to me severe anger/agitation and hatred are two different things, the former being more of a BP thing, and the latter being more of a BPD thing.

During dysphoric mania I can definitely become extremely agitated, but it's not personally directed at anything. Sounds that are too loud will piss me off. If the internet is running slow I will freak out. If someone is meeting me somewhere and is running 5 minutes late, I will start to boil over. But this agitation, as described, is just all over the place. And once a situation changes, my focus also changes. To me none of this is hatred, because I experience the feeling of hatred with BPD, and it is far more personal and obsessive than general BP agitation.

With BPD "hatred" or the "black" aspect of black/white thinking, if I'm not mindful enough in certain situations, I can wind up obsessively hating someone. I will basically have an urge to just destroy them (to put it honestly and bluntly) that will make me feel insane. Even when I am not being exposed to said-person, intrusive thoughts of them will haunt my mind constantly, and keep churning that hateful feeling.
