That is bad. But again: From the people I know, from the papers I read (yes really), from the videos I watched, it does not sound like BPD to me.
BPD-afflicted people are terrified to be abandoned, for one thing. Why would someone who lives that way actively antagonize the people around them? Yes, the emotional feedback loop if not broken out of can make people with untreated BPD show strong emotional reactions (anger, depression, crying) in the moment, but they snap back out of it, are usually ashamed afterwards, and don't press on with what can only be described as nonsense.
