I'm not a professional so take this post with a grain of salt. I am expressing my opinion as a peer only. This post is not medical advice.

Okay now that the disclaimer is out of the way here's my actual response:

From what you've described, it does sound like you may have a personality disorder in the cluster B category. Your case is atypical as you have traits of all four of those personality disorders but it seems to be that the histrionic traits appear to be the most prominent. Not all histrionics are the same, there's actually subtypes of HPD and one of them is with antisocial features(I forgot what it's called).

You don't sound all that narcissistic or borderline to me.

You may have more than one personality disorder as well, that's something else to consider. I have two myself, NPD and ASPD.

That's just my opinion, like I said I'm not a professional.

I hope you can get professionally assessed if a diagnosis is something you want. You can also send me a private message sometime if you want to talk about this in a more private setting.

Good luck.
