This was brought up on a different forum, but the speculation was a bit pointless. So I figured it would be easier to just ask those with firsthand experience.

When you're in the middle of a meltdown with a loved one, or you're in the process of splitting... Are those of you with BPD fully aware of what you're saying?

For an example: 

- Girl with BPD splits her boyfriend. She sends him several nasty texts, claiming she never loved him, has found someone else, and that he's a pathetic little bitch for thinking he even had a chance with her.

In that moment, are you fully aware of how hurtful and nonsensical your text messages are? Do you truly believe this man was never your boyfriend? Is this a calculated attack on your S.O.'s emotions to null the internal fear of abandonment, or a spontaneous train of emotion with no brakes?

Another example:

- A girl with BPD is questioned by her father regarding the details of a previous relationship of hers that had been posted online in a defamatory context. Facing certain embarassment and disciplinary action at home, the girl lies and states she had never even met the gentleman in question before accusing him of stalking her.

In this situation, do those of you with BPD truly believe you've never met the guy? Or do the emotions say "fire all nuclear missiles at the nearest target?"

For a non, this is the most challenging part of BPD to understand.
