mental illness classification?

okay so i know I've got depression, stress and anxiety and I've been diagnosed and now I'm seeing a specialist...but my sister?

well, my mum, dad, my brothers and me too, we believe she has some sort of illness but we seriously cannot pin point what it is exactly....

1. she does stupid/bad things then thinks she did nothing wrong; to the point that she basically forgets what happened or fabricates an entirely different set of events despite there being more than one person as witness

2. she has trouble backing off in a fight; as in she NEVER backs off, even if you're so angry or upset that you're backed up in a corner of your own room crying- she. will. not. leave. you. alone. Seriously.

3. she gets angry at EVERYTHING. literally. doors left open. things moved around. not being told EVERYTHING- as in even if it doesn't involve her and its what you did in your own time.

4. if you don't get angry and upset, she starts crying and saying things like 'i did nothing wrong and you all turned on me' or the more common one 'you're all crazy and you're making my life hell. i NEVER make any of you upset so why do you always turn on me!' and so forth..

5. the other alternative result to you not getting angry is she will get  aggressive. like, REALLY aggressive, as in hitting, scratching, hair pulling, breaking things and throwing things.

so there. anyone got any insights into her crazies? some suggestions would be nice. i think dad's just about ready to either kick her out of the house or call in the loony bin.
