I'm definitely not a doctor or an expert but some of what you've written reminds me of a relative who I think has BPD and also probably NPD. They also projected so much onto me and constantly called me a ''bad person''. Their deceit, particularly with money, was extreme. I won't bore anyone with the details. She was/is very manipulative. I'm sorry your sister is like this, as someone else said, she seems like the antithesis of you.

That ***** hurt me so much.

But I'm (apparently) ''just'' a whiny *** baby
thanks a bunch
