I posted that link because when I read it I thought about your situation. Yes you are right in how disorders can overlap. I have talked a lot about my ongoing challenges with my older sister in therapy and more than one therapist talked about her being disordered and the two disorders that were mentioned to me were borderline personality disorder and Npd.

I started reading about narcissists and so many things described so many of her behaviors including narcissistic rages. And my sister is also one that claims to have “special” powers.

It’s been like dealing with someone that is entitled and superior one minute and then poor me little victim the next. It is just that “disordered”.

It’s very mentally taxing to have to deal with a disordered person. They are emotional vampires. There simply is no true sense of calm. It’s just one drama after another.
