Can I still have BPD if this part doesn't apply to me. They put it first as though it's core.

'great difficulties in controlling ragefulness; they were unusually impulsive, they fell in and out of love suddenly; they tended to idealize other people and then abruptly despise them.'

None of that is something I do - I'm fairly even-tempered, not especially impulsive, don't fall in and out of love suddenly - especially not out, I'm realistic in my views of a person and don't despise them.
