Dear Ik09:

I am not a mental health professional, and even if I was, these public, online forums are not appropriate for making mental health diagnoses. Therefore, I can not diagnose you with Histrionic Personality Disorder. In regard to the two episodes you described, I believe that you behaved histrionically  during those episodes. Histrionic according to Merriam Webster. com means: “overly dramatic or emotional.. theatrical”.

It was suggested that your sister is narcissistic, if what was meant by it, is that your sister suffers from Narcissistic Personality Disorder (NPD), then again, only a professional, in a private, professional setting- in a doctor’s office following a few face to face meetings- can responsibly make this diagnosis. You can not diagnose her, neither can any member reading your third- person account of your sister’s words and behaviors.
